Hi,

Thanks for your answer.

Unfortunatly I am on vacation and won't be working until January. I will be trying your tips as soon as possible. I'll keep you updated!

Hi,

I will continue helping with this case.

To check if there is something wrong with the Thread network like this, can you set up a nRF Sniffer for 802.15.4 and send a sniffer trace of the issue?

Also, do you see the same for only 2 Thread devices, or is the range only shorter for many devices?

Were you able to test the range in open space? What was the results?

How much greater?

Hi,

I think it's a plaster wall. And it's really not thick so it should not be a too though obstacle.

I am testing my range with CoAP Packages: Every few seconds a device sends a Message to another device. If this Package reaches the other one, then this one sends an answer. Is the answer also successfully received, the device toggles a LED.

But I do not see a problem with my way of testing.

In this enviroment a few months ago we tested Bluetooth range with the same boards and achieved a higher distance. Could this be a problem with Thread then?

I wasn't able to test in open space yet because of the weather. But it is my plan to do so in the near future.

Hi Vincent,

If they are in the same room then 8-10 meters sounds short, especially if the devices are in line of sight. However, for devices that are in different rooms with a wall between them this could be expected range. What kind of wall is it, and do you know the material of it?

Have you tested in a large open space with line of sight for comparison?

Best regards,
Marte
