I am using a Q2698 module, F/W 7.50.0.A2, with NO OpenAT program loaded (AT+WOPEN=0). At first the flashing LED (network status one) did not even turn ON when the unit was powered up (with a valid SIM), and the LED remained OFF all the time. I then activated the flash LED using AT+WHCNF=1,1.
When I subsequently power up, the LED remains permanently ON until the unit registers on the network, which is correct. However, as soon as a valid resistration occurs, the LED turns OFF permanently instead of flashing. At this point the unit is definitely registered as checked using AT+CREG. Has anyone else had this problem with the flashing LED using the Q2698 module?
