IN865 - downlink not working in Class-A (MAC rxTimeOut) #4

Closed punee995 closed 2 years ago

punee995 commented 2 years ago

First of all thanks for the clean example.

I'm trying to do send downlink on Port 2(for led) but when I send downlink from chirpstack I'm getting IRQ_RX_TX_TIMEOUT can you give me some hint where to look ?

Also funny thing is In Class-C downlink works properly.

I believe this just means the gateway is not sending the downlink in the receive window. Class C leaves the receiver running all the time, so this isn't a problem.

Class A only listens for a downlink in precise time windows after a UL, so I'd check to make sure the LoRa network server and gateway are configured correctly. This is most likely a misconfiguration of the server and gateway.

What kind of gateway and server are you using?

danak6jq commented 2 years ago

I just re-built and test DL for LED control, port 2, and verified it works with my ChirpStack server. Odds are there is an issue with the server configuration there, also possibly with IN865 regional parameters.

Thanks @danak6jq, Downlink is working now, and yes It was because of regional parameters. en.STM32WL-Peripheral-LoRaStack_LORASTACK.pdf
