I'm working with the baseband data of the X2M200 module and I've found some errors in the documentation. 1. Enable baseband amplitude data: According to the Serial Protocol documentation the message format to turn on baseband data is: <Start> + <XTS_SPC_DIR_COMMAND> + <XTS_SDC_APP_SETINT> + [XTS_SACR_OUTPUTBASEBAND(i)] + <EnableFormat> + <CRC> + <End> But that does not work. And that's not what the example code does. According to my findings (And as James Citta has also pointed out), the following format works: <Start> + <XTS_SPC_DIR_COMMAND> + <XTS_SDC_APP_SETINT> + [XTS_SACR_OUTPUTBASEBAND(i)] + [LENGTH(i)] + [EnableFormat(i)] + <CRC> + <End> 2. Receiving baseband amplitude data: The format of the receiving packages of baseband data is according to the documentation: <Start> + <XTS_SPR_APPDATA> + [XTS_ID_BASEBAND_AP(i)] + [Counter(i)] ....... What I am getting is: <Start> + 0xA0 + 0x14 + [XTS_ID_BASEBAND_AP(i)] + [Counter(i)] ....... 3. Missing info on changing baud rate I'm receiving a lot of CRC errors (about 70% of all packages have CRC error). I wanted to try changing the baudrate of the module to see if that could help. But this is not documented. I figured it out through the example code, but it would be great to see if there are some baud rates that are recommended (according to the on-board clock frequency).
