RHF76-052 Lora module is born to be a serial LoRa module with firmware made for communication with an other uC.

But inside are an SX1276 and an STM32L051C8T6 and with the LMIC filesystem it is no problem to use this module with your own software

I did make a simple test print on my CNC just to do all the test.

I did get one of these boards link to page where to buy and checked out where to find som LoRaWan code for it.

Could not find anything but only som code here link to github BSFrance

Arcording to the datasheet it can run LoRaWan Link to datasheet

I did want to test this little Lora Node because of the STM32L151 and on the board there is a holder for litium battery.

I did use the files from waveshare as a start link to waveshare files

There is a clock issue and thts why the camera sometime make funny picture - I will make a new version when i do find the deep reason.

How to implement TouchGFX from ST

Here you can purchase STM32H743IIT6

If you do buy the 7 Inch LTDC screen you can here find the complete code for setting the TouchGFX up with LTDC, FMC and DMA2D in the STM32CUBEIDE version 1.4.2 with TouchGFX version 4.14

The touch screen is working and you can jump direcly to develop in TouchGFX

The DMA are only allowing buffers to remain in D2 domain so you have to define that ...

look in fileset and on video to see how to

I did struggle a bit with getting a stm32 Nucleo-L476RG and a RFM95 to join the TTN.

I did change to DF10 when joining ...se below picture ...

And then i did change back again to DF7 when it has joined ..see below picture

And it was very fast to get joined and send the first packet ....

If you want to use the LMIC and the cubemx you just have to change some lines in the main.c

Thanks to Piotr Siwy to inspire me.

Here you find the file set /sites/default/files/bluepill_ABP.zip

if you just want to change the OTAA example from the video the follow these few steps.

You have to set the keys in

IBM made a fine library for LoraWan - The Lmic library.

I see this libray as a easy way to get a LoRa node up and running, and it fit all the needs i do have.

But it was a little hard for me the first time to get it running on a ST microcontroller, due to the fact that using STM32CubeMX was not a option.

I decided to make some changes to the HAL file and to the DEBUG file and now it is VERY easy to get a SX1276 running together with any ST microcontroller.
