<br />
== Technical overview ==<br />
* The nRF51822 SoC supports Bluetooth 4.0 Low Energy and 2.4 GHz RF features.<br />
* The companion BLE400 mother board provides a battery holder, multiple power-supply options, accessible I/Os, an integrated CP2102 debugger, LEDs and user keys.<br />
* The evaluation kit consists of the BLE400 mother board and the Core51822 wireless module.<br />
* Recommended PC environment: Windows XP or Windows 7; nRFgo Studio v1.14 or later; Keil MDK-ARM Lite v4.54 or later; J-Link Software v4.52b or later.<br />
* For programming, install the nRF51 SDK; if installation errors occur, Microsoft .NET Framework 3.5 may be required.<br />
* blinky_example runs without an OS and executes directly after download; the LED visibly blinks.<br />
* ble_app_hrs additionally requires the S110 SoftDevice (Bluetooth protocol stack), e.g. s110_nrf51822_6.0.0_softdevice.hex.<br />
* For mobile connectivity, use nRFToolbox (Android) or nRF Utility (iOS); the app displays received data only after 19 characters are received.<br />

'''Commands and examples – verify before use:''' <br />
<syntaxhighlight lang="text"><br />
Send 'Y' or 'y' over serial to start broadcasting (LED0 lights up).<br />
Serial settings: baud rate 38400, 8 data bits, 1 stop bit.<br />
nRFgo Studio: select 'nRF51 Programming' > 'Erase all' before programming.<br />
Keil: open blinky.uvproj, press F7 to build, then click Download.<br />
For ble_app_hrs: nRFgo Studio > 'Program SoftDevice' > Browse (choose s110_nrf51822_6.0.0_softdevice.hex) > Program.<br />
</syntaxhighlight><br />
<br />
== Notes and version constraints ==<br />
* J-Link firmware may fail to cooperate with the Nordic SDK; in that case use nRFgo Studio &gt; 'Program Application'.<br />
* Initial output from the factory program is for self-test and can be ignored.<br />
* The mobile device must support Bluetooth 4.0 and have the appropriate app installed to detect the signal.<br />
* Compatibility with other boards and availability of specific firmware versions should be verified beforehand.<br />
