Hi,

The factors in my previous reply can affect stability, which is why I asked for more information about them. Please answer the following questions:

What other 2.4GHz items are in the area when you are testing?
Can you share a picture of your test setup?
How are you powering the boards?

Please also check if the readings are from a stable location, as the jumps in range seem to correlate well with the QoS data.

Best regards,

Marte

Hi，

It may be difficult to know the reason for unstable. I just want to know which factors affect stability and how to improve reliability.

Best regards

Hi,

Based on your picture you seem to have some serious issue with the readings. More information about your set up can help figure out the reason. What other 2.4GHz items are in the area when you are testing? Can you share a picture of your test setup? How are you powering the boards? Please also check if the readings are from a stable location, as the jumps in range seem to correlate well with the QoS data.

Hi,

I am still waiting on a response, but I will update you as soon as I can. Due to summer vacation in Norway we are short on staff, so increased response time is expected.

Best regards,

Marte
