Hello I try to use the GSm Shield (Quectel M10) without the Arduino Libs. This is working so far. But when I try to send Data via GPRS and TCP/HTTP there is no chance to send something.
I logged what arduino lib send and between the AT+QICSGP=1,"www....."
always is w(0x88).
What does that mean and must I implement this when using native uart?
I forgot to mention I dont use any arduino lib. I use only the plattform. I programm in C an use AVR Studio6
