Thanks Andreas, we understood very well.

Hi,

Yes various objects and their position will have an impact on the signal strength, both between the devices and outside the exact line of sight. This variation is as expected. Typically to get consistent radiated RSSI you need to test in a 100% stationary environment, which practically is only possible to get in an antenna chamber.

Best regards,

Andreas

Thanks Andreas for quick response.

In our case, both position and orientation were static for end node as well as for central node.So, only variable is communication channel, Am I correct ?

After pairing of central & end node, Will there also change in communication channel during any data transfer ?

Hi,

This is normal as the signal strength of the wireless signal will differ depending on the position and orientation of the devices, and the channel between them. There is no way to workaround this, but you might be able to get cleaner results by conducting more measurements and filtering the readings.

Best regards,

Andreas
