CBT connected but no packets
  • 0
  • Hi I just got my new CBT and managed to flash it after reformating my computer to linux but now i can't get any packets "/

    This is what I have done: Connected the CBT and used the Alpha App and it finds the CBT but thats it no packets when i connect with the OBD2 cable and I have tried 3 diffrent cars and have been able to connect to all 3 using a cheap ELM327 BT device and my phone :S

    But I can flash it with no problems or any problems connecting to it I tried to install CoolTerm but seems to not work with linux, it is also unsuported "/

    This is what i get:

    Can anyone help me? :)

  • No help so far?

    Anyway here is an update, I have found that the serial command for start dumping packets is 03 01 01 but this didnt help me but it responds to the 01 01 command.

    Also noticed that when I open the alpha app and log with a serial terminal it keeps repeating this: <code>{"event":"version", "name":"CANBus Triple", "version":"0.4.6", "memory":"950"}
    {"event":"busdbg", "name":"Bus 1", "canctrl":"4", "status":"0", "error":"0", "errorText":"No Errors", "nextTxBuffer":"0"}
    {"event":"busdbg", "name":"Bus 2", "canctrl":"4", "status":"0", "error":"0", "errorText":"No Errors", "nextTxBuffer":"0"}
    {"event":"busdbg", "name":"Bus 3", "canctrl":"4", "status":"0", "error":"0", "errorText":"No Errors", "nextTxBuffer":"0"}</code>

    And I got CoolTerm to start working but so far gtkterm is doing the job better :p

    Hey @UglyCoolboy‌ ! Sorry for the delay, I've been dealing with some house malfunctions. :((

    Did you connect to a CAN network and set the speed?

    The app constantly polls the hardware for the bus state, that's what you're seeing when you connect.

    If you do 03 (output packets command) you will not get any data if the bus speed has not been set. You can set the speed with 09 or do auto-detect with 01 08 or set it explicitly with 01 09. See the comments at the top of this source file for more info:

  • Hello good news I got it to work with the serial command :D

    Problem was that I was trying the auto-detect with the alpha program and that didn't work but with coolterm and the serial command it started dumping messages :)

    Many thanks now I am going to decrypt some message ids :D
