I have set an APN, sim card is ready.

It often says CME error: 30

What else shall I to set? Where is the problem?

Dear @Dominik_Holusa
Is the network redcap?
If yes, please execute the AT commands which I sent to you via Message.

Yes the network is redcap, I have already used your commands in the messages, but the problem remains.

Dear @Dominik_Holusa
Did you SIm card can register in the network of 23007?
For AT+COPS=?, just searching the network nearby.

Sometimes it did, but I have updated the firmware and now I have the problem that I cannot turn on full funcionality on module. AT+COPS=? doesnt show any networks. It says error immediately after typing that command without waiting.

Hello, do I need to have special kit for RM255C-GL to connect it to pc? I have older kits that work with other m2 modules like RM502Q, does it work also with RedCap module? Can RedCap module connect to standard 5G network?

Dear @Dominik_Holusa
For standard 5G module network, RM255C-Gl only supports 20M bandwidth.

It can work with older kits that work with other m2 modules like RM502Q.
Is it possible to capture log on your side?
