I am currently working with TYPE1SE Modem (LBAD0ZZ1SE) in the stm32l462re board. I am having an issue where the modem response to the command AT+CEREG? is "+CEREG: 0,4", where 4 means "Unknown (for example, out of Evolved Terrestrial Radio Access Net...

I need some help, I have found USART1 and USART2 however I can't understand where LPUART, USART3 and USART4 are. Also I don't understand what NC_UART0, RFT_UART1 and RFT_UART2 stand for. I know these last 3 are related to the modem type1sc. I also kn...

In the card that comes with the board says it has 16 Kbytes of EEPROM. Here is the link from the website (can't find anything about EEPROM): https://www.st.com/en/microcontrollers-microprocessors/stm32l462re.htmlAlso can't find anything about EEPROM ...

I believe it has an STM32L462RE inside as it says in the datasheet, however I was a little confused when I read the underlined sentence in the picture bellow. In the datasheet it says there is a M4 inside, however this sentence refers a M0. I just wa...

I've been trying to connect the modem for weeks (Not the truphone sim, a removable one). I would like to connect by talking with the modem directly (through the AT commands), however I have also tried the X-Cube-Cellular.Some AT commands don't work n...

Dear Solofo,If instead of configuring for NBIOT, I wanted to configure for LTE-M (cat M1), how would you write the command?Thank you :)Best RegardsSara

Dear SolofoI am not using the embedded SIM card, I am using a plastic SIM card from a local operator, trying to connect from Portugal. However this card only supports NB-IoT and you refer CAT-M. Does the Modem support NB-IoT? I read it supports LTE C...

I am having problems connecting to the network through UART. Is there someone who can help with the steps? Does it have to be through cli (image)? I have tried many times but it ends up sending at command to itself (image 2). Thank you.

AT+CEREG response is "+CEREG: 0,4", where 4 means "Unknown", even when connected to the Network. The modem is LBAD0ZZ1SE in stm32l462re board

Where can i find LPUART, USART3 and USART4 in the schematics of B-L462E-CELL1?

Does STM32L462RE have EEPROM? In the card that comes with the board says it does, however I can't find anything in the datasheet, nor on the website or the Hal driver files.

Does the Murata Modem TYPE1SE have an STM32L462RE inside?

How to connect a removable sim (not truphone) with B-L462E-CELL1? Some AT commands don't work neither in X-Cube-Cellular nor by talking with the modem directly through USART3.

Re: I need help with an issue regarding STM32L462RE (BL462ECELL1). How do you connect the modem to a network? I have been trying to use X-CUBE-CELLULAR. I flashed the binaries and know I can get some info from the modem, however i can't connect to the network

Re: The LBAD0ZZ1SE module includes a STM32L462REY6TR microcontroller, I'm not interested in using STM32L462 CPU peripherals I only want him to be as a modem who receives commands from outside to make communications is it possible?
