Thank a lot for your reply.
Sure, I will change my message and make sure , it is byte and not a human-readable value but I atill confuse about the convertion of my double value or char value to a bits/byte
But, the thing which still troube me. If I print
Serial.println(mydata)
my terminal return me an error.
exit status 1
call of overloaded ‘sprintln(uint8_t [64], int)’ is ambiguous
However, if I print
Serial.println((char *)mydata);
it print me an human-raedable value.
So does mydata value are already in bytes (no human-redable)? because (char *) should convert in readable value, no?
Morever, mydata is declare in this way
uint8_t mydataAll[64];
But for sure, I have to review this part of my code (and remove the ’ {}:" ’ which consist of a json format
Tnank a lot
