Also by using my handheld RF spectrum analyzer, I see two wave bursts when the Join Request is sent and also when Join Accept is received from gateway. So gateway does pass on the Join Accept from TTN to node.
Some more thoughts:
It may be possible that for the node, the RX window after the Join Request is sent is not long enough or may be not exactly at the right time when the Join Accept arrives.
- Is there any way I can check if the RTC is working fine with the millisecond accuracy?
- Is there any way I can stretch the RX window? where can I update this setting? I know that the value must follow the LoRa specs.
- Is there any latency from gateway? how can I check that?
Thanks
