LoRa WAN node for TTN. Based on Murata CMWX1ZZABZ-091. Written in c and STM32CubeIDE

Looking for someone who could help me with my project. It is Lora node which should be powered on battery. It should be working on EU 868 band according to limitations of the band. The device suppose to react on interrupt from an accelerometer and also with adjustable intervals do other measurment and send data. * OTAA. I can c programming but i lack experience and i need someone to set up the whole framork with LoraWAN node so i can program the rest myseld or with You as a tutor.
Managed to run lrwan example which comes from STM but so far it’s to big chunk for me to bite.
