No CAN packets incoming in random can mode off

[Shavo650]

Hi. Thank you for this sniffer. It's only one which i found and it works... almost :) So i made .exe file using your python code, because I can't install python at my laptop (i couldn't fix this so i gave up). App works but only if i upload sketch with #define RANDOM_CAN 1. In this mode i get true packets from car and these generated ones. But I can't send any packet back to the car. In RANDOM_CAN 0 i don't get any packets at all. My Arduino works fine, i tested it with examples and my own code too.

same here to me

maybe we need a delay also for RANDOM_CAN 0

// Main
void loop() {
RXcallback();
#if RANDOM_CAN == 1
CANsimulate();
delay(100);
#endif
}

My communication is working using an other program ( https://github-com.translate.goog/ludwig-v/arduino-psa-diag/tree/master/arduino-psa-diag?_x_tr_sl=fr&_x_tr_tl=it&_x_tr_hl=it&_x_tr_pto=wapp ) for Peugeot.

I have set this can sniffer the same, 500k Can bus speed, clock 8k... but its not showing incoming sniffed packages.

So you guys are saying that the arduino and the wiring works for sure, because you can send and receive packets with the CAN library examples? And, with RANDOM_CAN 1, if you open the serial port within the ArduinoIDE you see the generated messages AND some real packets from the car as well, but with RANDOM_CAN 0, nothing? This is pretty weird.
