If anyone interested here is a link to ESP32 port of 2.1.9 firmware. As 8 base station are managed by GPIO pins you can build a system with some standard boards with limited soldering – what actually I did …
ja.charer – thank for your effort, but I’ve a problem
Everything is compiled without errors and when I uploaded to “Helltec ESP32 Kit Lora” it doesn’t boot at all. What I change is the SDA and SCT pins, because this Helltec module have included led display on that ports. Is this change of SCL and SDA can cause problems?
