Hi and good day to everyone, I have a problem with wAP LR9 kit which can't receive join requests from a LoRa node, specifically the cndingtek DC510 people counter sensor but other node works just fine. I've tried many things such as changing the band: kr920,as923,us915, changing node's deveui, and frequency offset also does not work. I've contacted dingtek's support, but they seem can't find the problem with their sensor, and they said the sensor works with other gateways.
Does anyone have any idea or solution to this?
