Short range with Coded PHY

Hi Dominik,

I would strongly suggest to get hold of a nRF52840 development kit.
It's easier to develop your application and you can achieve better range with the Dev Kit.

The dongle is provided as the backend hardware for the sniffer and for nRF Connect for Desktop BLE. It's not the ideal platform for development and RF testing.

The range with the dongle is limited compare to the DK.

Hi.

Yes, I can clarify that dongles are PCA10059.

During the test, one dongle was connected to my notebook as I was walking and second dongle was connected to USB hub on my desk. Is it a problem that dongle was connected to PC or?

I have also tried set the power to +8dB with commands in prj.conf:

CONFIG_BT_CTLR_TX_PWR_ANTENNA=8

CONFIG_BT_CTLR_TX_PWR_DYNAMIC_CONTROL=y

but it didnt help with range.

We dont have nRF52840 Development kits unfortunately, we are starting with dongles.

Thanks for answer.

Hi Dominik,

Could you please clarify the nRF52840 dongles you used is PCA10059 board ?
Did you connect them to a PC ?

Please be aware, due to the size of the dongle the RF performance may not be the best. It's not made as a reference design.

Our suggestion is to test using two nRF52840 Development Kits (PCA10056) instead.

Also please double check the TXPower configuration. Please take a look here: How to set TX power to maximum +8dbm for advertising as well as when connected
