Hello guys! I am using WLR089U0 module but it only joined once. I remove the power and connect it again but the device cannot join. I am using OTAA. I tried disabling “Enforce” duty cycle on my gateway side but nothing works. Here is what gateway console shows to me: [image] Here is what device …

Serial output gives me “No Free Channel Found”. I am using a 16-Rx channel gateway (Kona Macro from Tektelic)

Does your device use subband 1? [image] MarcoAndrade: No Free Channel found That means your device is sending join requests too rapidly and needs to wait for the next attempt.

Yes, I also tried with subband 2 and I am getting the same error. I found that the gateway has a lot of CRC fails. And Rx packet error rate: 0.78. Rx packet error rate is decreasing as more packets are received

[image] MarcoAndrade: I found that the gateway has a lot of CRC fails. That typically means that either you’re picking up a lot of traffic from other non-TTN systems, or else your node is too close to the gateway and overloading it. Posting the actual join requests reports received by the ga…

Yes, the end-node and gateways are less than 10 meters. I don’t believe that is the problem because when I use Xplained Pro, it joins correctly. Only with the node I developed the problem appears randomly. Suddenly it joins correctly but most of the time not. Here are the join requests reports. Fr…

[image] cslorabox: It looks like you may have an RSSI of -49 which is “shouting in your ear” loud and suggests you may want to move the systems further apart. [image] MarcoAndrade: Yes, the end-node and gateways are less than 10 meters. So they are both likely to be shouting at each ot…

[image] MarcoAndrade: "frequency": "902900000" That is not a frequency used by TTN in the “North America (902-928 Mhz)” band you said you are trying to use. To see the actual frequencies used, look at: https://www.thethingsnetwork.org/docs/lorawan/frequency-plans.html Both your gateway and …

Might be helpful to look at the LoRaWAN header file settings of the WLR089 project. At one stage I did a file compare between supplied LoRaWAN libraries and found the new library and code added a random channel feature…except it was coded to 64 random channels, but the gateway only has 8. LoRa b…
