SO,
U1 was not flashed, it's a big mistake on my part. I had seen the documentation, but I thought it was an old procedure for flashing the STM32. :?
After the flash, the QCA was recognized. RX/TX were at 1.6V. :D
I was also able to get pyplc to work in EVSE mode.
Next step, return to ionity ...

I went back to ionity.
CP is ok, PWM is detected at 5%

But no communication. :cry:

Here are the oscilloscope tests

CP :

Input Modem RF (Test to R25 resistor) :

RX_N / RX_P / RXIN_N / RXIN_P : 0V
TX_N / TX_P / TXOUT_N / TXOUT_P : ~1.2V ...

Thank you so much,

This allowed me to detect that my CP was disconnected, I had a micro cut on the PCB. I tested with my granny EVSE, and the PWM was detected.

I deleted L5 and L7 which were present, but perhaps too quickly, because on the last diagram, it was still present. My card comes from the ...

I need your help please.
I have a 4.1 focci, with the fixed on PP: 330ohm pull up + 47k
Flash STM et ESP32 : OK
Communication with the QCA chip seems ok: opmode = 100, and the rgb button is solid green.
I plugged into an Ionity terminal, but nothing happened. The charger did not detect the ...

Off chance, is it possible to include an esp32 chip, in order to run the OI esp32 webinterface ?

Hmm, you won't be closing the vehicle contactors with the maybe 10 mA on the conn check pin. Will need some external 12V supply.
I use focci as-is with CHAdeMO (see QCA7000 thread) with 12V supply from vehicle"cigarette lighter" output

Hello,
It only works on your Touran, right? :(
How ...

Hello,

I'm very excited about this project, and I'm getting started.

In order to make a CCS to chademo adapter (leaf 2022), I started an assembly based on raspberry 4 + TPLink 4015 + WaveShare CAN hat + LCD2004 display.

I'm trying to get the battery voltage with an ODB bluetooth dongle, but I'm ...
