NRF52811 with BLE Long Range Example

This blog is to show how to setup the BLE long range demo on the nRF52811 chipset.

On the Nordic webpage, S140v7.0.1 is the official support the BLE long range stack on the nRF52811.

The size of the S140v7.0.1 is 156KB (including 4KB MBR). It means that the size of the application fw cannot be larger than 192-156KB = 36KB.

I did the quick demo code and placed it at

https://github.com/jimmywong2003/nrf52811-ble-long-range-demo

The FW size of the Central / Perpherial are around 18-20KB given the following conditions

  • Optimization with size,
  • Without debugging information
  • Without RTT log

Meanwhile, if you would like to estimate the RANGE, the RSSI signal strength and Packet Success Rate % would be shown through UART terminal at the Central side.

If you have any comment, welcome to notice me.
