Hello gemalto!
I have connected a microcontroller to the concept boards TX and RX pins so i can send AT commands to the modem. I am waiting for the +PBREADY URC before i connect to the network(using AT^SISO=0). But it fails to connect with the message "connection failed". However if i insert a delay of 0.3 seconds after i received +PBREADY it all works just fine.
It seems a bit strange to me?
Hello,
You didn't write what exactly is done before AT^SISO=0 command but I assume that this is not the problem here as you connect successfully after the delay.
The '+PBREADY' URC means that the module has completed reading data from the SIM card. To make any connection it ***** to be registered to the network. To check if the module is registered you can use AT+CREG or AT+COPS commands.
