Long range issue SPSGRF-868 module with send/receive data with AES encryption.

[Nh.1]

Hi,

We are using SPSGRF-868 module in our project, With following settings of RF module operating @868 MHz Send/receive data without Encryption we are able to achieve 20~25 meter distance and working fine. But Send/Receive the data with encryption we are not able to achieve 20~25 meters distance.

We followed below settings for with/without encryption:

Date rate: 3.6 Ksps

Frequency deviation : 9.918 KHz

Channel filter : 50.961 KHz

is it as payload size increases range is degraded and is it need to be change above settings for Send/Receive data with encryption to achieve 20~ 25 meters distance?

Thanks,

Nagaraj
