- illegalsmile 8y agoAbsolutely! While it's not my preferred method of control, you can send AT commands encapsulated in SMS to update/troubleshoot BGAN terminals.
- jpm_sd 8y agoIridium modems use it too!
- clort 8y agoIts embedded into GSM modules; Phones need it to do anything, to check firmware versions, to send and retreive SMS messages, to make calls etc. I used it to control the 3G dongle I had (basically, a GSM module in a stick). Most times the device will act as a serial device.
- askvictor 8y agoAlso used in the esp8266 when it's configured in wifi-serial mode.
- pooppaint 8y agoAt commands are used for many nonmodem things too.. Bluetooth adapters, zigbee adapters, HC12 transceiver, other various proprietary devices tied to a UART in addition to LTE, GSM/GPRS (I guess technically some of those are modems but they’re pretty far removed from the original design)
- 3chelon 8y agoAT commands are still in use inside your smartphone. On an iPhone, when the main CPU wants communicate with the baseband chip to make a call or send SMS or whatever, it literally sends AT commands. In fact, one of the earliest iPhone jailbreak exploits relied on a vulnerability in the AT command interpreter inside the baseband.
- kazinator 8y agoCommands that have to prefixed with AT are still in use. Most of the actual commands after the "AT" part are not recognizable to someone who knows dial-up modems; they have nothing to do with the Hayes set other than the AT prefix/misfeature.
