https://devzone.nordicsemi.com/f/nordic-q-a/2730/how-to-not-use-bleHi all I just have to use 2.4MHz with nRF51822. I don&#39;t neel to BLE and have to use full flash memory for application space up to include BLE stack. If I control it, I want to know how to not use BLE. It dosen&#39;t need to be loaded BLE stack.

Of course you don&#39;t need to load the SoftDevice to use the 51822 as a general purpose Cortex-M0 processor. Sure, there are easier ones to use out there but you get the cool SoC functionality as well.</p> <p>Anyway, you will want to study chapter 16 of the nRF51 series reference manual on the RADIO hardware if you plan to use it. Here is an excerpt:</p> <blockquote> <p>The RADIO contains a 2.4 GHz radio receiver and a 2.4 GHz radio transmitter that is compatible with Nordic&#39;s proprietary 2 Mbps, 1 Mbps, and 250 kbps radio modes in addition to 1 Mbps Bluetooth Low Energy mode. The RADIO implements EasyDMA. EasyDMA in combination with an automated packet assembler and packet disassembler, and an automated CRC generator and CRC checker, makes it very easy to configure and use the RADIO.</p> </blockquote> <p>Let us know how you do!</p> <p>Dan</p><div style="clear:both;"></div>
