Hi JimmyWrong2003,

Thank You so much for sharing a nice example. I will test on my end this example and share the results in a few days!

You can find the example at my github which I did before.

https://github.com/jimmywong2003/nrf52-ble-range-estimator

It has the nRF52840 and nRF52833 example.

Hello,

SDK 15.0.0 did not have support for the nRF52833 IC, so porting the project would require some additional patching of the SDK as well as setting up the project. It would be better to start with the latest nRF5 SDK (v17.1.0 at time of writing) and either port the long range sample to it, or make a new one based on existing sdk examples. The 'pca10100' configurations you will find in this SDK are configured for the 52833 ic.

The diffs below show the few changes you can make to the Nordic UART Service Client & UART/Serial Port Emulation over BLE SDK example to use the long range mode if want to try that.

devzone.nordicsemi.com/.../peripheral_5F00_uart.diff

devzone.nordicsemi.com/.../central_5F00_uart.diff

(note: for more range you can also increase the TX output power to +8dBm like in the example you referred to)
