@Crowdsourcer said in Arduino MKR NB1500: lukt niet om te verbinden.:
@Stefan-de-Lange Yes, I am first sending the command as text, then after receiving the @ I switch to binary to send the raw data.
//So I first open a UDP channel:
//Then I send the USOST command using ascii printing
//Subsequently I receive a “@” from the SARA module, then write binary data
I can’t judge your code. I can only see you do not read ‘@’ (or it’s hidden in some other function) but start writing immediately. I suggest you implement this synchronously and read back the ‘@’ before writing data.
