Hello,

I've managed to setup a exs82 device to communicate with UDP and send and receive binary payload, and now I'm waiting for a SIM card that will allow me to use NIDD, though I fail to understand how I can manipulate binary data with the AT+CSODCP & CRTDCP commands. From the few examples I've seen of those functions being used people always used ASCII, is there a way to enter some sort of data **** or to provide ASCII hex that would be sent as binary over the air ?

Hello,

There is no data **** where you could send raw binary. But the data field is described to contain string of octets. And this parameter shall not be subject to conventional character conversion as per +CSCS.

So that would be what you need - a hex string that should be sent as binary.

For instance with at+csodcp=2,5,"1234567890" we'd send 0x12 0x34 0x56 0x78 0x90.

Regards,
Bartłomiej
