Here is one problem confused me some days:
1. I send some data with LoRaWAN, so it will start RxTimeoutTimer to detect if timeout, and will set radio timeout 0xFFFF as default.
2. Normally, the radio will raise IRQ_RX_DONE irq, that mean receive data done from gatway.
3. But sometimes, the radio will raise IRQ_RX_TX_TIMEOUT irq, even it's not timeout.
That is my question: what will cause radio raise IRQ_RX_TX_TIMEOUT irq ? Thanks.

Here is work flow:
1. Device send data to Gatway.
2. Gatway will send data to Network Server(NS)
3. NS will send respond when receive data come from Device
4. Device will receive respond come from NS.

No data reception completes *within* the timeout window. Start of reception doesn't clear/restart the timeout.
What's the actual measured/elapsed time between you starting the reception, and you getting the time out?
