Description
With the same code as issue #105, udp.peek() is always returning -1.
Here's the serial output:
Attempting to connect to the modem
Attempting to connect to the GPRS Access Point Name
Packet sent
Awaiting response
udp.parsePacket 48
udp.available -48
udp.peek -1 <--- expected decimal 36 (first byte in response)
The code is the same as #105 and quite long so I won't post it again.
