Problem with CAN - no data if there's no USB connection

Post by quebec »

Hi.
I've encountered strange problem. We're using MK2 Pro module with bluetooth and telemetry modules, connected via CAN to EmuMaster ECU. Everything was working correctly - I've written CAN integration script based on examples on wiki and configured everyting - until today. Data from the CAN is not logged, and it's not sent to smartphone via bluetooth, UNLESS I connect RCP to my PC via USB. If i connect USB and switch on 12V power - everything is OK, even after disconnecting USB. If I just plug 12V on, the GPS, telemetry and bluetooth modules are all working, but there's no CAN data. To bo honest, I have no idea what's going on.
One more thing I've noticed is that there are new informations in RCP app - "131unexpected id", and there was also "168unexpected id".

You can download RCP config file from here: https://drive.google.com/file/d/0B_NVb0 ... sp=sharing

I would really appreciate any hints. We're on Shell Eco-Marathon right now, and we're unable to log anything :(

//edit: i've also uploaded new firmware to RCP - nothing has changed.
//edit2: Update - RCP doesn't need connection to PC, it just needs power via USB - for example from power bank. I think that there might be a problem with voltage regulator - I can't think of any other explanation.
