RAK8213 mPCIe freezes after AT+QCOPS command
I have recently acquired RAK8213 mPCIe card for NB-IoT connectivity. I have attached it to a windows host using the companion USB-mPCIe adapter from RAK as well. I manage it through Putty and relevant AT commands.
I initially searched for GSM/LTE-M/NB-IoT networks using the AT+QCOPS=7,0 (or AT+QCOPS=7,1) commands and indeed I got 3 different public GSM networks but no NB-IoT (although I know there is a private network I established myself present...). For the above tests I used the default configuration (factory settings).
Then, I started playing with the configuration in order to see if I can capture the NB-IoT network as well (I know this is on B20).
Some of the commands I issued:
Unfortunately I could not get any network through AT+QCOPS.
So I restored the initial settings, but after that every time I search for a network the module seems to freeze.
I tried the AT&F0 command, which is supposed to do some kind of reset, but again no luck.
Any ideas on that?
Hi, my way to test NB-IOT is below:
1.Firstly, insert the sim card with NB-IOT service(I use China Telecom)
2.set baud with: AT+IPR=115200&W
3.echo off with: ATE0
4.check sim card with : AT+CPIN?
7.Network Search Mode Configuration:0->Automatic,1->3->LTE only ;1->Take effect immediately with AT+QCFG="nwscanmode",3,1
11.search net, it will cost at least 150s: AT+COPS=? connect the net with NB-IOT.

@nero Many thanks, seem ok!
