short range

[Zsolesz]

Hi!

I have more nrf52840 boards with pcb antenna. I would like to ask u. Maximum data change distance with 8dbm tx power is 5-6m . Is it normaly?

Hi,
Yes.

Hi,

 

Well, 8-9m when connecting to your phone is not a whole lot, so if you have similar poor performance in both ends of the link, further reduction is expected. What range do you get if you run the same application on a DK?

 

Best regards,

Andreas

Hi,
Sorry but i have one more question.
I read this blog: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf52840-dk-range-testing-with-ble-zigbee-and-thread-protocols-at-0-4-and-8dbm-transmit-power-settings

Based on this. Will i be able to communication in ble@1Mbs mode between two nrf52840-dk module at a distance of 50 meters?

Hi,

 

It depends on the environment you are testing in. If fairly noise free and line of sight then yes, if in a dense office building in a busy city then probably no.

 

Best regards,
