No advertisement in nrf51822 usinf s130 softdevice

[Anonymous]

I am trying to advertise some data using the s130 softdevice to my MS49SF2 (nrf51822 based module ) and then flashed the hrs example code to it..

Still I couldn't find any advertisement..

any suggestions are appreciated..

are reset pins in use while the nrf ble modules are in working condition..?

Do you have another iPhone or Android device that you could test it with? I have had a similar situation where I cannot find the nRF device on my iPhone, but I can find it on an Android phone. Maybe that could help?

nope..

not shown either.. while using the nrf51 kit (development board), both on iPhone and android works fine, the only issue is when getting to the standalone application..

It could be that the MS49SF2 does not have a 32 kHz external oscillating crystal. The SDK you have downloaded assumes that an external oscillating crystal is used. This could be the reason why you cannot detect the MS49SF2 on your Android phone. If you really want to use the MS49SF2, you need to use the internal 32 kHz RC oscillator. See (this link) for benefits of having an external oscillator. (This link) might also help.
