Looking for gateway compatible with B-L072Z.

Hello community,

Currently, I have Lorawan gateway: p-nucleo-LRWAN1 and Lorawan node: B-L072Z LRWAN1.

I'm looking forward to suggestions from you, which company gateway and node will be better than this current gateway and node. with current devices, I'm facing data rate as well as long-distance communication. In the current node when I fill a 242-byte buffer and try to transmit data it only transmits data at SF7 and SF8 and not at SF9,10,11,12. At this SF I'm getting empty packets. And at distance of 50 meters only from gateway SF turns from 7 to 12.

Thank you.

There's no reason why what you're using shouldn't work.

What software are you using on the B-L072Z-LRWAN1?

The over-the-air payload size is significantly smaller at the higher spreading factors - maybe the problem is in your splitting of that "large buffer" ... ?

EDIT:

It also affects time-on-air - so perhaps your transmission is being blocked due to time-on-air limits ?

Thank you for your response @Andrew Neil

I got your point, and as this picture/google says we get SF7 till range of km. But as I go beyond 50 meters SF drops from 7 to 12. How can I get a better data rate with a range of 1 km?

@Andrew Neil If you get some time please refer this https://community.st.com/t5/stm32-mcus-wireless/not-getting-mention-speed-of-lorawan/td-p/639109. I have detailed everything into this post.

Thank you.
