I'm seeing similar problems to others in getting highly unreliable connections to the network. I *VERY* occasionally get LED3 and LED4 to blink simultaneously, but it's very rare, and generally something times out and the board loses that connection shortly therafter.
This is tested in Southern California from various points roughly from Irvine, CA to San Diego, CA. This is the home of Qualcomm, so I'm assuming the network isn't the issue...
I can't run any AT commands against the asset_tracker code as it never gets past the nrf_cloud_connect.
Running the at_client code I can do a AT+CGMR and that gives me:
mfw-m1_nrf9160_0.6.8-30.alpha
Any help would be very appreciated. Thanks.
