Several Networks with using RFM95HW

klgklg:
Hi All.

If on an object is installed several networks how I should set a centre frequences of each network for avoid influence each other?
Addresses of gateways of each network are differ.
All devices of each network are based on an RFM95HW modules (868MGz).

Thank You.

Very vague so cannot answer.

How many is 'several networks' and what are 'objects'

The RFM95 does not have a concept of an 'address' unless you are using some sort of protocol that you have not revealed.

Give a much more complete explanation of what it is you are doing.
