Hi @shane bourgeois

Which library are you using? Do you have a link to the code? I am wondering whether the library is able to handle VE.Hex messages coming directly after the VE.Direct text frames.

Kind regards,

Im using the "VeDirectFrameHandler.h" from https://github.com/cterwilliger/VeDirectFrameHandler/tree/masterfor
for my test code i had been using https://community.victronenergy.com/questions/33570/smartsolar-settings-for-vedirect-rx-tx-communicati.html

I really like biozor code from Sep 07 2023 esp8266.ve.direct3.zip
Thank you for your help!

Hi @shane bourgeois

You need to make sure that the hexRxEvent function only returns true when inbyte == '\n':

bool VeDirectFrameHandler::hexRxEvent(uint8_t inbyte) {
  return inbyte == '\n'; // stubbed out for future
}

Otherwise there might be problem with hex messages that are transmitted immediately after a text frame.

Kind regards,

Hi @shane bourgeois,

Can you give a zip file with all the code?

And can you give a dump of all the raw byte values that the esp is receiving?

Kind regards,
