LoRa Basic Modem proposes an full implementation of the TS001-LoRaWAN L2 1.0.4 and Regional Parameters RP2-1.0.3 specifications.

LoRa Basic Modem embedds also an implementation of all LoRaWAN packages dedicated to Firmware Update Over The Air (FUOTA):

• Application Layer Clock Synchronization (ALCSync)
• Remote Multicast Setup
• Fragmented Data Block Transport
• Firmware Management Protocol (FMP)
• Multi-Package Access (MPA)

LoRa Basic Modem offers extended services:

• LoRaWAN certification process
• Geolocation with LoRa Edge chips
• LoRaCloud features such as Stream, Large File Upload, Device Management or Almanac Update

LBM library code can be found in folder lbm_lib.
Please refer to README.md to get all information related to LoRa Basics Modem library

Under lbm_examples folder, one will find a few examples on how to use the LoRa Basics Modem stack.

• Hardware Modem (Implements a hardware modem controlled by a serial interface)
• Periodical uplink (joins the network and then sends periodic uplinks and each time the button is pushed)
• Porting tests (Allows to verify if the project porting process is correct)
• LCTT certification (to run LoRaWAN certification)

The examples are targeted for the NucleoL476 kit featuring an STM32L476 micro-controller. For further details please refer to lbm_examples directory README file.

To build the periodical uplink example targeting the LR1110 Semtech radio the following should be executed on the command line:

make -C lbm_examples full_lr1110 MODEM_APP=PERIODICAL_UPLINK

Under lbm_applications folder, one will find 3 specific applications that are using LoRa Basics Modem stack.

• A ThreadX Operationg System running on STM32U5 (lbm_applications/1_thread_x_on_stm32_u5/README.md)
• A LBM porting on Nordic NRF52840 (lbm_applications/2_porting_nrf_52840/README.md)
• A Geolocation application running on Lora Edge (lbm_applications/3_geolocation_on_lora_edge/README.md)
