I have experience similar issue, I have a RAK2245 and RAK2287 (SX1301 vs SX1301) and the first captures way more packets than the second. I am looking various forks from this repo to see if there is any improvement that I can implement locally
Hi @vikasrohal , what packet forwarder are you using? could you print the output when the concentrator SX1302 starts? I am interested to see the rssi_offset
in my case I suspect it could be part of the problem, I am using the basicstation
as packet forwarder and it is not honoring the rssi_offset
of -215.4 set in the station.conf
, configurations may if you're using a different paket forwarder, but in some place of a you should define a rssi_offset based on your board's desing.
Since I believe it is more related the specific forwarder I am using I have opened an issue in that repository:
https://github.com/lorabasics/basicstation/issues/80
@vikasrohal I found my issue to be in the node side, it was using a wrong preamble in the code, LoRaWAN establishes that it needs to be 8 Symbols for preamble and in my case the node had a code bug that reported more than that. It made the Gateway to discard that message. After I fixed the Preamble length in the node's code, I had no more packet drop.
Apparently the rssi_offset
has nothing to do with this issue, but still looking forward the TheThingsStack to avoid pushing this for the LNS protocol and avoid hardware issue.
Closing this issue, as it was not related to this project
After multiple testing I have observed that there are some LoRa packets drops in gateway designed from sx1302 , in comparison with sx1301 for which I have also attached some screenshots. There are min of 5% packets drops in sx1302 . I hope that someone have faced similar issue can help me in some way. thanks for help in advance.
