    I am running the X4M200 with an ESP32 and started getting a lot of CRC mismatch. Only started today. Anyone experienced this?

  3. Hi Lenny,
    My module seems to be stuck in the XTS_SPRS_READY loop. I'm using the exact same classifications provided on the Xexthru arduino documentation. I tried changing the baud rates and the serial ports but nothing seems to work ( the tx and rx led's on the mega doesn't even blink while the xethru seems to boot up and fire all led's). I tried removing bits and pieces from the code and it seems like there is no acknowledgement from the radar. Any ideas on how to solve it ?

    Any chance i could have a look at your code ? :D
