[Anil Snadhan]

Hi 

I am facing range issue in transmitting and receiving data over ZigBee in nrf53833, how can i improve the range maximum i  am  able to recieve signal from around 35 feet ,if walls are between it is even less

Hi Anil,

The range you are describing is quite typical for indoor applications.

Have you tried using the DK and compared the results?

Increasing the output power is one option.

Hi Håkon,

Apologies for reviving this old thread, I thought it'd be better than creating a new one (or?).

How do I increase the power output? Is it a feature available only on the DK or is it possible on the NRF52840 Dongle as well? Or do I simply need to provide more input power? (currently it's 2.4V)

Best regards,
David

Is your project also a 802.15.4 project? In that case, check out nrf_802154_tx_power_set in the API:

This is available regardless of the DK/board.

Setting TX output power to the maximum should at any voltage in within the operating supply voltage range, 1.7 V to 5.5 V.

It is often better to create your own case, as each project is unique. You could always link to the cases you find relevant.

It seems that the signal strength is indeed better now. And I much appreciate the other info you provided, this is very helpful for a beginner like myself. Thank you!
