'''Commands and examples – verify before use:''' <br />
<syntaxhighlight lang="text"><br />
Y oder y senden → Start... wird empfangen, Gerät sendet aktiv; LED0 leuchtet.<br />
Serial-Einstellungen: Baudrate 38400, 8 Datenbits, 1 Stopbit.<br />
nRFgo Studio: nRF51 Programming → Erase all vor dem Flashen neuer Programme.<br />
Keil μVision: blinky.uvproj öffnen, F7 zum Kompilieren, Download-Icon zum Flashen.<br />
ble_app_hrs: erst S110-SoftDevice flashen (s110_nrf51822_6.0.0_softdevice.hex), dann App kompilieren und laden.<br />

== Notes and version constraints ==<br />
* Exact slot dimensions are not specified in the source; confirm with the supplier.<br />
* If JLink firmware fails to cooperate with the Nordic SDK, Keil download may fail; use nRFgo Studio as fallback.<br />
* SDK installation errors require installing Microsoft .NET Framework 3.5.<br />
* Phone connection requires the phone to support Bluetooth 4.0 and have the appropriate app installed.<br />
* The app displays received data only after 19 characters are received; shorter sequences are not shown.<br />
* Version-sensitive steps (nRFgo Studio ≥ v1.14, Keil MDK-ARM ≥ v4.54, J-Link Software ≥ v4.52b) must be verified before starting.<br />
