1. AT COMMAND

XM-AT is RaymonIoT developed firmware for mass production in IOT application, aim to easy integrated

into customer’s products and cut down the R&D cost. It finishes the job of throughput data transfer between

UART and network. XM-AT command can easily finish data sending and receiving via Wi-Fi or BLE. Parameter

setting can also be done.

XM-AT provides different AT command for application such as Wi-Fi, TCP/IP, Bluetooth, MQTT, HTTP and

Ethernet command.

Currently, X-C13SL,X-C13SG,X-C13SM,X-C15P these modules support XM-AT firmware.

1.1. UART Setting

1. After module power on, default is throughput mode, users input “+++” and “a” to change into AT

Command mode via UART.

2. Recommend to use SecureCRT or UartAssist tools for AT Command test tools.

3. Default module UART parameters are following:

1.2. Switch Throughput to AT Command Mode

UART send “+++” to module, it will response with “a”, then UART send “a” within 3 seconds. Module will

response with “+ok” to indicate AT command mode. Following as example:
