AT command firmware for MultiTech Dot devices.

Fork of mDot_AT_firmware by MultiTech

Dot Library Not Included!

Because these example programs can be used for both mDot and xDot devices, the LoRa stack is not included. The libmDot library should be imported if building for mDot devices. The libxDot library should be imported if building for xDot devices. The AT firmware was last tested with mbed-os-5.4.7. Using a version past mbed-os-5.4.7 will cause the build to fail. The library used with the AT firmware has to match the mbed-os version.

Dot Library Version 3 Updates

Dot Library versions 3.x.x require a channel plan to be injected into the stack. The Dot-Examples and Dot-AT-Firmware do this by defining a macro called "CHANNEL_PLAN" that controls the channel plan that will be used in the examples. Available channel plans will be in the Dot Library repository in the plans folder.

Revision 20 and earlier of Dot-Examples and revision 15 and earlier of Dot-AT-Firmware should be used with Dot Library versions prior to 3.0.0.

Fota Library

Th Fota Library must be added to compile for mDot 3.1.0 with Fota support. Latest dev libraries and 3.2.0 release will include Fota with libmDot/libxDot.

AT Firmware Description

This AT Firmware is what ships on mDot and xDot devices. It provides an AT command interface for using the mDot or xDot for LoRa communication.

AT command documentation can be found on

The firmware changelog can be found here. The library changelog can be found here.

Dot Libraries

Dot Library Limitations

The commit messages in libmDot-mbed5 and libmDot-dev-mbed5 specify the version of the Dot library the commit contains and the version of mbed-os it was compiled against. We recommend building your application with the version of mbed-os specified in the commit message of the version of the Dot library you're using. This will ensure that you don't run into any runtime issues caused by differences in the mbed-os versions.

Stable and development libraries are available for both mDot and xDot platforms. The library chosen must match the target platform. Compiling for the mDot platform with the xDot library or vice versa will not succeed.

mDot Library

Development library for mDot.


Stable library for mDot.

Import librarylibmDot-mbed5

Stable version of the mDot library for mbed 5. This version of the library is suitable for deployment scenarios. See lastest commit message for version of mbed-os library that has been tested against.

xDot Library

Development library for xDot.


Stable library for xDot.

Import librarylibxDot-mbed5

Stable version of the xDot library for mbed 5. This version of the library is suitable for deployment scenarios.
