[marekbm]

i finally started with video how-to. the first one is probably not so important because everybody who has this module and it's already works then he knows it. but i plan to add all regarding the module settings and other features.

so here it is.
it's in Czech but you can turn on English subtitles .

new video. how to set baudrate properly.

Is it possible to get it to show artist and song title in the

DIM

as well? I really wanna buy a Pioneer with Android Auto, or the BluePower Android unit when it is released, but this is so easy! I got a GROM BT unit already, but for the price you charge, I might just buy yours instead!

[245 V8]

Noen som vet om det er bare og putte inn et gammelt sim kort eller må det vere et tvilling simkort til telefonen?

[Jimbojama]

Hvis du tenker på den originale telefonmodulen (uten modifiseringa som her omtales) bruker den et hvilket som helst aktivt simkort. Om du har eget abb til bilen, eller vil bruke tvillingsim er opp til deg selv.

it's possible to implement but it will not convenient. the text is possible to show instead of the operator name (connected device). if this is active then buttons on the steering wheel are mapped to the

PHM

instead of the radio. so if you see the text then you can't change the track or change the volume on the radio.

small changes

v2017-11-28_1
Updates
- Bluetooth: Some names of configuration files has been changed (again). The reason is due to merge the names for all my BT products:
- - license upload: “bt_license.bst”
- - settings: “bt_config.bst”, “bt_config.bgt” (settings request), “bt_config.txt” (received settings)
- - system information: “bt_info.bgt” (information request), “bt_info.btg” (received system info)
- - error log: “bt_error.btg” (log request), “bt_error.btg” (received log)

- how to update the module (updated order, so it's as third on the list)

[locked]

Yeh.. firmware update failed.. My phone said "File could not be sent" and now the

PHM

just display "Please wait..." forever.

How to fix?

[marekbm]

what was the transfer status before it was failed? was it failed on the begining (nothing was sent) or it was failed during the process?

if nothing is send then just turn off the ignition, lock the car and wait at about 5 minutes (check it if it start operate). if something was sent then it depends on the bootloader version. if the bootloader version is older than 2017-10-14 then you have to remove the

PHM

out of the car and reflash the BT module via USB (let me know and i will send you a steps how-to).

It failed in the end, when aprox. the whole file was sent it failed.
if nothing is send then just turn off the ignition, lock the car and wait at about 5 minutes (check it if it start operate). even after 12h sleep it's "Please wait..." if something was sent then it depends on the bootloader version. if the bootloader version is older than 2017-10-14 then you have to remove the

PHM

out of the car and reflash the BT module via USB (let me know and i will send you a steps how-to).

Bootloader is older, the process have failed a couple of times so It's still an old version, probably from june/july.. So, please send instructions. See e-mail in my signature.

BT module - recovery via USB
preparation:
- remove

PHM

out of the car and remove the main cover
- unplug the 30pin ribbon cable from BT module
- install sam-ba (SAM-BA v2.xx for Windows) software on the PC with windows (http://www.microchip.com/development...m%20programmer)
- reboot the computer
- download the latest fw for BT module (https://drive.google.com/drive/folde...Ep4ai15NU1lTVk)
- rename the "btphone_p2v2.btb" file to "btphone_p2v2.bin"
- images mentioned bellow are available here: https://photos.app.goo.gl/JRtm124XQcS9CF2p1

recovery process:
- connect BT module to the PC via USB
- make a short on "JP2" (by metal tweezer, wire, ...)
- wait at around 10 seconds and release the short on "JP2"
- wait at around 20 seconds, run "SAM-BA" application (on windows 10 as an administrator)
- on the app at second line choose "at91sam4s2-ek" and click on "Connect" (figure "init - 01")
- on the next window (figure "init - 02") click on the button marked as red and then choose the "btphone_p2v2.bin" file
- click on "Send File" (figure "init - 02", marked as green)
- after the file is send then the message appears (figure "init - 03"). choose "No".
- click on "Execute" (on figure "init - 02" marked as blue) and then close the app.
- unplug the USB out of BT module, wait 10 seconds and plug it back. LEDs should start blinking somehow and after a while only the blue is blinking ("BT_B").
- send the following files to the BT module via bluetooth: "boot_loader.btb", "bt_config.bst" (do not forget to set the communication speed properly, you can also set the other things), "btphone_texts.bst"
- unplug the USB cable out of BT module and connect the ribon cable back
- put the

PHM

back into the car

the license is missing on the module so it will always disconnect any device after a minute. turn on the

PHM

and you will see the code instead of connected device name. make a picture and send it to me . after that i will send you a license file.

note:
in the package "BT Phone P2v2 - v2017-11-28_1.zip" the file "bt_config.bst" is badly named as "btphone_cfg.bst" (will fixed in next release). in this case rename the "btphone_cfg.bst" file to "bt_config.bst.

[marekbm]

again some improvements
v2017-12-13_1
News
- Bluetooth: Possibility to manage paired device list via files
- - “bt_pair.bgt”: After the file is send then you will reveive “bt_pair.txt” file. This file contains list of paired devices. Each line is the paired device (<Name>;<ID>;<Key>).
- - “bt_pair.bst”: This file contains the list of paired devices. If empty then all devices will be deleted. Use the "bt_pair.txt" and remove the device (line) which you want to remove out of BT module. Then send it as "bt_pair.bst".
- Bluetooth: You don't need to be connected before you want to read the device settings, ...
- Bluetotoh: If the BT module don't find any device after the second loop then it stops searching. It makes easier to pair the new device if it's not possible at beginning.
- Modem: Added protection and notification against wrong instalation, if the SIM cable is plugged into

PHM

. You will see the permanent "SIM ERROR" message on the dashboard. Contacts are not shown, you see the settings phonebook list instead (not possible to use after the device is connected). Connect the device, listen the music, receive or dial calls is available.
Fixed
- Bluetooth: If the second device is enabled it's not automaticaly connected.
- Bluetooth: Sometimes the file sent from the BT module was not finished properly.
- Bluetooth: The file from the BT module has been always sent to the first device also if requested from the second.
- Firmware package: Wrong names of the configuration files.

PS: i'm curious how many people will see the "SIM ERROR" after this update.

[marekbm]

news which new users will like them .
v2017-12-15_2
News
- Modem: Modem communication speed is now automatically detected.
Updates
- Modem: The default modem communication speed is now set to 19200Bd (facelift models).
- Bootloader: Some updates regarding communication speed.

PS:
if you have wavecom version in the pre-facelift model then it will not work properly for a while. so do the following steps:
- after the firmware update wait for a while (error on the radio disappears)
- turn off the ignition and lock the car.
- wait at around 5 minutes
- turn on the ignition and wait for a while, if the green LED on

PHM

stops shining, turn on the

PHM

again.
- wait until it start operate properly
- now update the bootloader

PS2:
the bootloader update is required for everybody. the link to videos is above.

[Jimbojama]

Tha last update I did was 24.02.2017. What files do I need to update to get the latest version in my car? Hoping I don't have to send all the updates in between!

[marekbm]

Tha last update I did was 24.02.2017. What files do I need to update to get the latest version in my car? Hoping I don't have to send all the updates in between!

it should be ok if you flash directly the latest fw. the firmware first and then bootloader. if something wrong then it's possible to fix via USB (it can happen). if you have a laptop then it should be the best option for this situation.

[marekbm]

the part managing calls has been changed quite a lot.

now it works like this:

incoming calls (does not matter if the first or the second connected device):
- if the call is rejected, then it's terminated
- if accepted on then

PHM

(if it offers it) then the call is connected as a HF via

PHM

- if accepted on then device then the call stays on device

outgoing call:
- if dialled on the

PHM

then the call is created on the first connected device (possible to switch via "**#")
- if dialled on the device then:
- - if not active any call then it's connected as a HF via

PHM

(if ericsson modem or the it's the second device then

PHM

starts ringing, if rejected then call stays in the device)
- - if already active call (connected as a HF) then the new call stays in the device

call terminating:
- if the red button on the

PHM

(or the steering wheel) is pressed then the call connected as a HF is terminated.
- if terminated on the device then it's also terminated on the

PHM

(if connected)

call switching between

PHM

and the device:
- if you want to switch the call from the

PHM

to the device then select Earphone or Speaker on the device (audio options during the call). the call will stay in the device and it's terminated in

PHM

.
- if you want to switch the call from the device to the

PHM

(HF) then select Bluetooth on the device (audio options during the call). if ericsson modem or the it's the second device then

PHM

starts ringing, if rejected then call stays in the device

2 active calls or 1 active and 1 incomming:
- if 2 active calls (each on the different device) and the call connected with the

PHM

is terminated as the first then the

PHM

offer the connection with the second. if ericsson modem or the it's the second device then

PHM

starts ringing, if rejected then call stays in the device
- if call is active and connected with

PHM

and some incomming call is on the second device then:
- if accept the call on the device then call stays in the device.
- if current active call is terminated then the

PHM

offers accept / reject the of the incomming call.


in the shortcut:
where you do the action, there it will affect.

not so possitive news for the iPhone owners. i have an piece for the testing. after some tests i do not recommend it to use with another connected device (the connection start to be unstable, from time to time it causes Bluetooth modem restarts, ...). the worst scenario is if the iPhone is connected as the second device and you make a call or somebody calls to the device. if iPhone is connected as an only device then there is no problems.

i hope that this text makes a sence. if not then i apologize and let me know.

---------------------------------------

v2018-05-06_1

News
- Bluetooth: Now it’s possoble to connect call from the second device with HF.
- Bluetooth: If current call is terminated and another call on then second connected device is active then the

PHM

Fixed
- Bluetooth: If call on the second connected device starts then module is unstable.
- Bluetooth: Call management rewrited.

[Morgis]

I really like this update. Thank you

[marekbm]

many bugs fixed.

v2018-05-28_1
Fixed
- Modem: If the field from the settings phonebook is choose then nothing happens. If not possible to activate the bootloader (actualization) then send the file "boot_loader.run" as first to activate it from the device and wait at around 10 seconds after that.
- Bluetooth: iPhone device: If the device is manually disconnected (from the settings) then it's not fully disconnected.
- Bluetooth: Call management update (especially iPhone). But still not recommended to use iPhone with another device on one time (Causes instability if active call on the both devices).
- Bluetooth: After the second device is disconnected then the first device is not fully re-connected.
