nRF52840-DK - Long Range ,data rate 125Kbps

[Josh_1]

Hi

Please advise when I can find firmware for nRF52840-DK which can send advertising packets or any data packets at data rate 125Kbps and +8dBm output power

I have two nRF52840-DK one will be Central and the other is the Peripheral , the goal is range test .

Please advise.

Thanks

Hi,

Unfortunately I`m not software expert so I need to verify ,if I want to change the power i need to do it by changing the number "8" below? 

+ err_code = sd_ble_gap_tx_power_set(BLE_GAP_TX_POWER_ROLE_ADV, m_advertising.adv_handle, 8);

Do you know if this firmware (8dBm,125Kbps you offer is fit to achieve the best range between the boards? 

Thanks

Hi,

Yes, it will set the output power to +8dBm.  I can't think of any other SW changes that would improve range.
