I am looking for help to develop code for SX1280 Nodes and Gateways for TTN. The benefits of 2.4GHz is faster data rater and no fair usage limits on broadcasting but the range seems to be slighly lower but still very acceptable.
I have designed a board along the lines of the TT-GO LoRa boards which has an ESP32, header pins for OLED, GPS and BME280 and is being used on high altitude weather balloons. The boards take an RFM95 868MHz module but I have also had a few more manufactured which will take a NiceRF LoRa128 module which has an SX1280 chip. We are using one of the boards as a gateway with the single channel gateway code from Things4U for testing but in Africa where the balloons are being launched by university students, they have a commercial gateway connected by 4G to TTN
Anyhow, Id be interested in developing an ESP32 breakout board with the LoRa128 module on board and make the Eagle design files and gerbers freely available so people can get their own boards made and maybe offer a few on fully assembled on Tindie at a reasonable cost but what I need is some help in terms of coding.
I have found a SX1280 library written by Stuart Robinson but I dont really know where to start incorporating this into either the node or gateway code and am hoping someone will be interested in helping with the coding. I will send you a pair of the boards with ESP32 and LoRa128 modules onboard in return for your assistance and to enable you to test the code etc. The code needs to be open source and freely available along with the PCB design files and hopefully, this exciting development from Semtech can be put to good use.
Please get in touch if this interests you. Thanks, Steve.
