hello in the past ive set up 3 of units esp8266 with Victron Energy SmartSolar MPPT 100V 20 amp 48-Volt.
I have a new unit here tryingto pull information and i cant seam to get anything.
Anyone else have issues with the library or maybe its the newfirmware for the MTTP100/20?
Moved to modifications forum. More chance of an answer.
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,
Thiemo van Engelen
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!
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,
