(C)2013 Semtech-Cycleo
This directory contains the sources of the library to build a LoRa Picocell Gateway based on a Semtech LoRa multi-channel RF receiver (a.k.a. concentrator). Once compiled all the code is contained in the libloragw.a file that will be statically linked (ie. integrated in the final executable). The library implements the communication with the concentrator embedded MCU through a serial port.
The library also comes with a bunch of basic tests programs that are used to test the different sub-modules of the library.
Those programs are included in the project to provide examples on how to use the HAL library, and to help the system builder test different parts of it.
This software is used to set up a LoRa concentrator using a JSON configuration file and then record all the packets received in a log file, indefinitely, until the user stops the application.
This software is used to check the reliability of the link between the host platform (on which the program is run) and the LoRa concentrator register file that is the interface through which all interaction with the LoRa concentrator happens.
This software is used to send test packets with a LoRa concentrator. The packets contain little information, on no protocol (ie. MAC address) information but can be used to assess the functionality of a gateway downlink using other gateways as receivers.
This software is used to set LoRa concentrator in Tx continuous mode, for spectral measurement.
This software is used to jump to the PicoCell Gateway bootloader for programming the MCU with a new firmware. Please refer to the readme of picoGW_mcu repository for more information about MCU flash programming.
This software is used to obtain the unique id of the PicoCell gateway (the 64 bits unique id extracted from the STM32 unique id registers).
A detailed PicoCell GW user guide is available here
- HAL: fixed an issue in the lgw_reg_r()/lgw_reg_w()/lgw_reg_rb()/lgw_reg_wb() functions to write the register page before reading/writing any register to avoid conflicting with MCU register page setting.
- HAL: updated MCU firmware version to match with picoGW_mcu V0.2.1 release.
- HAL: Fixed bug in lgw_mcu_receive() which was preventing from fetching more than 2 packets simultaneously.
- HAL: reverted AGC FW to version 4, as v5 was necessary to fix a HW bug which has been fixed since rev V02A of the picoCell reference design.
- HAL: fixed a bug lgw_com_send_command() function to prevent from hanging when writing on the COM link was not possible.
- HAL: fixed memory alignment on FSK syncword configuration.
- HAL: fixed a wrong copy size and position of MCU unique ID in lgw_mcu_get_unique_id().
- HAL: disabled some logs.
- HAL: fixed MCU command wrong size in lgw_mcu_commit_radio_calibration().
- HAL: fixed MCU reset sequence to wait for MCU to complete reset and reinit the communication bridge before exiting. This is to avoid issues when restarting the concentrator after exit.
- HAL: code clean-up/refactoring
- HAL: serial port configuration to handle both USB or UART communication with mcu.
- util_boot: only used to jump to the MCU bootloader.
- util_chip_id: no more command line parameter, just print the PicoCell GW unique ID on the console.
- HAL/util_*: added a parameter to lgw_connect() function to specify the COM device path to be used to communicate with the concentrator board (tty...).
