MTQ-LSP3-B03 Device Guide
Refer to +CFUN in the
AT Command Reference Guide
for other sleep options.
Note:
If using +CFUN commands, then reset the device via the PC13 (3G_ONOFF) toggle low to high to bring the
radio out of +CFUN sleep mode.
Developing with an MTQ in Mbed
Build applications written for the MTQ are built on top of the Arm

Mbed

library and can include the MTSAS
library for easy cellular radio use.
The MTQ ships with AT pass-through firmware, which directly connects the cellular radio to the external serial port
on the MTUDK2-ST-CELL developer board. The firmware:
Runs at 115200 baud by default to match with the cellular radio’s default baud rate.
Prints debug messages from the debug port at 115200 baud.
Allows users to increase or decrease the application’s baud rate by entering a plus (+) or minus (-) character
on the USB debug port. Issuing a plus or minus character on the USB debug port changes the external serial
port speed as well as the speed of the link between the processor and the radio. The speed of the USB
debug port on reset is always 115200 to match the radio’s default regardless of the baud rate used at the
time of reset.
Uses RTS/CTS flow control on the serial connection to the radio and on the external serial connection.
Enables RTS/CTS flow control on terminal emulators used with the AT pass-through firmware.

Documentation
Arm Mbed is a free, open-source platform and operating system for embedded devices using the Arm Cortex-M
microcontrollers. The Mbed website provides free software libraries, hardware designs, and online tools for rapid
prototyping of products. The platform includes a standards-based C/C++ SDK, a microcontroller HDK, and
supported development boards, an online compiler and online developer collaboration tools.
Programming the MTQ Microcontroller
With the MTQ and the MTUDK2-ST-CELL developer board, use the Arm Mbed ecosystem to program the
microcontroller. Compile in the cloud or locally, copy the resulting binary file to the Mbed USB drive, and reset the
MTQ.
All MTQ software is open source.
