Hello,
I am facing a huge problem for three days, and I don't have any beginning of a solution...
I made a PCB with an STM32L476 and a LoRa chip SX1272. I am using the code given by ST ICube LoraWan. After a join success, I start a custom timer and I send data on my LoRa server. Everything works, I can see the join success and the data on my server, but it works ONLY with the ST Link V3 plugged. It is repeatable, when I unplug the st link V3, sometimes the join request works, sometimes not. Some data are not received, and it looks like the program is blocked.
Maybe I am missing something, an option I need to check...
I am using IAR 8.42.2.
If someone have an idea, because I am completely blocked...
Thanks.
