Hello, I've just built a bluebus for myself And the BootLoader （V1.3 from GitHub） and firmware V1.3 （from Bluebus website） just successfully flashing But the display screen of the car just turned into a black screen when Bluebus plug in I just realized that I missed the configuration of the Bluetooth module, May I ask if this is the reason why the bluebus is not working, and if so, I just downloaded the BlueBus_Provisioning_1_3_2 form here, but I'm not sure how to flashing it in to the bluebus

Check the resistance from I/K-Bus to ground -- sounds like there's a short.

The missing Bluetooth config is not the reason for this, though.

It's 80KΩ， looks this resistance is no problem, and the power LED lights up which means at least IBUS can turn on the power

And I just run bt_test.bat in BlueBus_Provisioning, it gives me IBUS: ERROR, Does that mean chip TH3122 has some problem？

tedsalmon commented 5 months ago

Does your TH3122.4 have “1936” written on it?

AdonisAAA commented 5 months ago

I have 1935 on it

Right, I misremembered! Thats part of a bad batch of TH3122.4s — get an ELMOS 10026B instead. Your best bet is to desolder one from the sport steering wheel multi-function control board.

Thank you so much, let me try to get a 10026B and try it
