Bad Range using RFM95 and STM32L476RG

[Zeeshan123]

How can I achieve optimal range for LoRa node-to-node communication? I'm using the RFM95 module at a frequency of 932 MHz but experiencing very poor range—data transmission cuts out at only 4 feet. I have a compatible antenna, which is properly soldered as well.

Hello @Zeeshan123 

This depend on the module you are using for LoRa communication (the RFM95 module). So, it will be a good idea to check with the manufacturer of this module. The 4 feet to me seems to be very strange for me.

Best Regards.

Yes, its strange for me as well. I dont what might be the issue probably the module is the bad or the firmware needs revisions

I don't think so. And even if it is, is not something that ST delivered. So, you need to check with the person who worked on this FW.

Best Regards.

I have downloaded the library provided by ST. I guess there might be bad chip or some hardware issues
