LAIRD BL600

[Maik]

Hi,

is it possible to use this module from LAIRD in connection to the nordic SDK - i installed the softdevice hex but the hrs example for s110 is not running properly ?

Thank you very much.

On the Laird BL600 modules, the Whisper Mode is enabled by default.

#define WHISPER_MODE_PIN 20 #define WHISPER_MODE_ON() { SET_GPIO_HI(WHISPER_MODE_PIN); } #define WHISPER_MODE_OFF() { SET_GPIO_LO(WHISPER_MODE_PIN); }

Then disable Whisper Mode before you start advertising. It does not actually matter when you do it but by default Whisper Mode is enabled and your device will be really quiet with an RF range < 20 cm.

Using the macros above, you can enable/disable Whisper Mode and notice the variation in RSSI reading (for this you could use the sniffer or nRF Master Control mobile app with RSSI charting).

From hardware integration perspective, PIO-20 on Nordic chip (nRF51822 pin # 28) which is SIO_20 on BL600 (Bl600 pin number 27) shall be kept NC.
