FOTA using DISCO-L475VG and latest version of LoRaServer

1

Hello everyone,

I am working on a project to update a device over LoRa. I have followed the very well documented example (thanks Jon): https://github.com/ARMmbed/mbed-os-example-lorawan-fuota

My first trial was to use the test loraserver and the logs can be checked in the image attached, I have the feeling that only messages on port 15 are being handled by the test server. However messages related to port 202, 201… necessary for starting the multicast session previous to the FUOTA are not being logged in the output.

As a trial, I have configured the LoRa server multicast group and Firmware update job in the server so that I am “replacing” this test script: https://github.com/ARMmbed/mbed-os-example-lorawan-fuota/blob/master/fuota-server/README.md with the new functionalities of LoRaServer. However I am receiving this error after setting up the firmware job for my device: (left side of the image)

If someone can have an idea of what can be going wrong with my attempt of performing FOTA it would be much appreciated the help.

Thanks in advance,
Best,
Teresa.

Hi teresama,

I also faced the same problem. I’m still figuring out this…
https://github.com/ARMmbed/mbed-os-example-lorawan-fuota/issues/10

As far now i figured out that the port 202 msg is posted in topic “application/*/devcie_eui/join”.
but this is only for the first time.
After that i dont see them any more on the MQTT topics.

The messages are coming over the “LIVE LORA FRAMES” page but not on the “LIVE DEVICE DATA” page.

if you can share your analysis it would be also helpful.

Thanks & Regards
