I am developing a LoRaWAN node with my own hardware and firmware. I am now testing the transmission of uplinks. On the gateway, I can see each uplink in the ‘live traffic’, On the application server, I am missing some of the frames, ie. not every frame seen on the gateway seems to be accepted by …

[image] strooom: Is there a way to monitor on the LNS why it is rejecting those frames ? Depends, mostly not. What MCU & radio are you using? What LoRaWAN MAC / stack / firmware are you using? What authentication method to the LNS are you using (ABP or OTAA)? What gateway are you using? …

[image] strooom: On the gateway, I can see each uplink in the ‘live traffic’, On the application server, I am missing some of the frames, ie. not every frame seen on the gateway seems to be accepted by the LNS. Similar issues have (only) occasionaly been reported in the past - to investigate…

MCU = STM32WLE, it has an SX1262 inside (if you are interested, here is a link to the hardware The LoRaWAN stack is my own. I’m using ABP (no need for OTAA at this time for our application) Gateway is the The Things Indoor Gateway, connected with WiFi to my home’s AP Gateway is provisioned in TT…

Here are two screenshots of how the traffic is different on gateway vs application server [gateway] [application] packet from 13:17:34 is shown correctly on both packet from 13:19:34 is only shown on gateway packet from 13:21:34 is only shown on gateway packet from 13:23:34 is shown correctly o…

First, do you observe the FUP? Second, take a look at the downlinks to check why you are burning gateway transmit time like no tomorrow. Third, why implement another stack when there are proven versions that adhere to the standard (and took a lot of effort to get right)

[image] strooom: The LoRaWAN stack is my own. Which MAC commands have you implemented so that your device will respond appropriately to requests from the LNS to ensure good community use of the network? Any reason why you reinvented this very complex wheel? What’s wrong with the STM32CubeMX…

Ok, thanks for all these good hints. I spent a lot of time investigating the LoraMac from Semtech/ST. Personally I disagree that it’s solid and easy to reuse. I will set up my own TTS to get some more logging while building and testing the LoRaWAN implementation.

[image] strooom: Personally I disagree that it’s solid and easy to reuse. I’ve ported loramac-node to a new controller and am working on a second one and while it does take time to get familiar with the code, it is the best choice if you need a sx1262 compatible stack in my opinion. At least …

[image] strooom: Personally I disagree that it’s solid and easy to reuse. The vast majority of the commercial devices use it. It isn’t the best signposted code in the world, but then LoRaWAN has many many nuances, particularly when you get in to multi-region support, so there is a blizzard o…
