Hi,We are developing a LoRa application using the STM32WLE5JC chip. The product is to be implemented for multiple deployment regions (EU, US, AU and AS). We have a problem with the US configuration. When a device sends a join request, the first attem...

Hi,I'm working with the STM32WLE5JC mcu and Cube firmware 1.13.0. Can someone explain how the module/stack implements adaptive data rate? I can see from lora_app.h that it is enabled by default, but exactly how is it implemented?The screenshot is fro...

HelloWe are working on a product using the STM32WLE5JC MCU. The features a magnetic switch that generates interrupts (specifically a low to high transition) which is meant to wake up the MCU from STOP2 mode. What is the ideal way to do this? We have ...

We're using the STM32WLE5JC to develop a LoRa-based project. We are looking into testing our sensor in a very specific environment with very specific settings - the TX power and Spreading Factor. Can these two be manually configured?Thanks

Hello, I am working on a project using the STM32WLE5JC module and STM32CubeIDE for development, with firmware packge v.1.3.0.We are currently running EMC tests at a test facility, and they have requested for the ability for the device to send data ev...

Thanks @STTwo-32 With regards to setting the enabling/disabling ADR, can it be enabled/disabled on the fly? We are looking into manually adjusting the TX power and Data Rate in scenarios where connectivity is proving difficult.

Hi @STTwo-32 Thanks for the clarification.For the ping pong scenario to be used, the test house needs the two devices to be on fixed channels. For example device 1 will be fixed on channel 1 and device 2 will be fixed on channel 8.How can this be con...

Thank you both for your detailed feedback and input @STTwo-32 and @Andrew Neil !

The network is definitely not an issue here - we just need to transmit.I was not aware of the Ping Pong example code. Will it be able to send data that quickly?

For the US example, the idea is that we would send a downlink message to the device to switch the active region before we ship it (we are based in the EU). We would then confirm the device is sending uplinks via our US Gateway, located in a test room...
