Description
ExpressLRS is an open-source high refresh radio control link that has proven resilient to interference while maintaining a maximum achievable range at that rate with low latency. Designed to be the best FPV Racing link, it is based on the Semtech SX127x/SX1280 LoRa hardware combined with an Espressif or STM32 processor. We build the first known open-source implementation of ExpressLRS in GNU Radio by building upon the existing GNU Radio implementation of LoRa (known as gr-LoRa), to support frequency hopping. We propose to investigate the resilience of ExpressLRS in the presence of different types of RF interference. ExpressLRS is designed to operate in both 900 MHz and 2.4GHz. We will present performance evaluation results from both software-in-the-loop and hardware-in-the-loop tests based on the ADALM PlutoSDRs and COTS platforms that support the ExpressLRS protocol.
