Hi,

I’m pretty new to this in sending commands to the modems.

Our devices are using the AirPrime Modems: MC9090, MC8795, MC8790.

I would like to find out if there is a way to send a AT command to the modem via SMS to reset or reboot it.

Hi,

Short answer to this is no. I know some competitors offer this in the form of hidden AT commands to turn the functionality on which enables you to send AT commands to them over the air but there is nothing like this on board the units you have quoted.

It represents a major security risk.

Regards

Matt

What is the nature of your “devices” ❓

Could the “host” part of your “device” recognise the incoming SMS, and do the reboot?
