running ble_app_blinky_c and ble_app_blinky on two seperate nRF52832DK boards. It works, but why do I not see any RF on nRF Connect on my Android smart phone??

I have the precompiled code running on two seperate nRF52832DK PCA10040 1.2.1 boards.  The example appears to do exactly what it said it would do. However I cannot detect any RF from either board using the nRF Connect app on my smart phone and was wondering why.  If it is working there has to be RF through the air at times, how do I detect this, Is there an app besides nRF Connect that will detect this? Thank you

Hi

The nRF Connect app will only detect advertising devices. Once the blinky devices are connected they will no longer be visible to nRF Connect. 

If you only power up the ble_app_blinky board, and leave the ble_app_blinky_c board turned off, you should be able to discover and connect to the device from nRF Connect. 

To detect devices in a connection you need a BLE sniffer. The best sniffers are expensive tools from the likes of Ellisys and Frontline, but there is also a free sniffer provided by Nordic that uses a Nordic devkit to sniff nearby devices.
