No uplink received with WaziHat (low signal) #133

Open cdupont opened 3 years ago

I am trying with the WaziHat V1.3, RPI3, ISO 2.1.1. I send messages with WaziDev and this sketch: https://github.com/Waziup/WaziDev/blob/master/examples/LoRa/LoRaWAN_LPP_LMIC/LoRaWAN_LPP_LMIC.ino

However the messages are not received with WaziHat. Logs:

Raising the SF to 12 on WaziDev gives better results. https://github.com/Waziup/WaziDev/blob/master/examples/LoRa/LoRaWAN_LPP_LMIC/LoRaWAN_LPP_LMIC.ino#L26

However the signal is still very weak: RSSI -89dBm (very weak signal).
