What get shown when you call
gprsFuncs.at.debug()? From what I can see, it looks likeCIPSENDbehaves the same way whenCIPMUX=1was used - which is was in your case. It's possible it doesn't like the newline after\rthough... It should returnSEND OKif all has gone well.It looks like it might just send back the result data without
+IPD, which would make it harder for Espruino to get the data.I think you need to send the
AT+CIPHEAD=1command when initialising to make sure that+IPDgets prepended to any data.
