Hi Solofo, thank you. I'm not intended to use Truphone. I'm using a plastic card. In my country only NB-IoT is available. The modem supports the NB-IoT technology for the removable card, right? If yes, how do I perform the network registration?Best R...

Hi Solofo,Thank you for your help. I want to perform the network registration, I'm not sure which are the AT commands sequence to achieve it ( the Murata documentation, only explores the AT commands functionalities). I thought that configuring the ba...

[B-L462E-CELL1] The modem doesn't respond to some AT commands

I'm working in the B-L462E-CELL1.I'm trying to communicate with the modem via Uart.GPIO TX and RX pins have the label"MDM"which I assume mean MODEM.Before sending the command"AT"I power up the the modem by level up the pin"MDM_PWR_EN_OUT.It doesnt respond

I have a B-L462E-CELL1 board, which has a CatM1/NB-IoT Type1SE modem. What I did: Put the SIM card, then connected the USB to the USB uart connector and sent the "AT" command, without a response. What am I missing?

I have a B-L462E-CELL1 board, wich has a oled display. I want to turn it on, but i dont know the vdd pin. The datasheet is very brief.
