ChirpStack V4.12 FUOTA multicast won't complete

ChirpStack FUOTA Server
1

Hi,

Been trying to complete a test FUOTA campaign in the ChirpStack Network Server V4.12 using LoraBasic Modem periodic_uplink example, i did all the configuration steps implied by the documentation of LBM, but when i create the FUOTA task and register my gateway and device on it, it starts the multicast setup but it doesn’t work.
The device joins and sends uplinks.

I really don’t know what i done wrong, so i seek help.

My device is a Stm32 L476RG with sx1262, gateway Dragino lps8v2 and AU915 region.

Best regards,
Luiz

I eventually discovered this by myself, but it was really the problem with the class C device profile as said in the topic you mentioned.

Hello, good to hear that you solved your issue. I use the same gateway with its built-in CS V4, I use the STM32WL55( and the STM32WLE5) but I’m facing problems during fragmentation, if you could share your configurations on CS( and on the firmware if there is any special configurations) on this Topic, I’ll be very grateful to you.

Thank you

Which SDK are you using? my fuota did complete but the firmware did not change in the end, in the chirpstack is shown as everything went ok.

I use the STM32WL-1.3.1 Package(with STM32CubeIDE) and with V1 FUOTA Package. I just recently came to the same point where all the packets were received(after 28 Minutes), but I notice that there is no CallBack Function to inform CS that the operation is done.

If I press the reset button, I don’t think the Running Image will be swapped with the FUOTA-Image.
