Hi,
We are considering using the SC20-AX smart module with yocto linux for production in a new product.
I have a few basic questions that i didnt manage to get a clear answer to and would like some help with.
- Does the module come with any sort of linux image pre-installed already or do i have to upload my own to every unit? I am talking about the bare module itself, not the EV board.
- What is the simplest way to interact with the module without using a screen? Is it possible to just connect it with UART serial and remote to its terminal?
- From where can you send the AT command to the GSM module? Can i do it directly from the terminal? Is there an example program on the image or do i have to do it from the UART pins on the chip?
Any help would be apprechated. Thank you
