RE: nRF BLINKY compatible firmware using Zephyr Bluetooth APIs

Hi @vikrant8051 would like to run this demo under Zephyr on the Nitrogen board.

I have tried compiling the app in the latest version of Zephyr (1.14.0) but the major problem is the two macros BT_GATT_CHARACTERISTIC and BT_GATT_DESCRIPTOR seem to have changed. BT_GATT_CHARACTERISTIC now wants 6 parameters, and BT_GATT_DESCRIPTOR is no longer present. I tried the simple fix of 'combining' the two since it appears that the newer BT_GATT_CHARACTERISTIC is simply the combination of the two older macros.

Other minor changes the file ../prj.conf needs CONFIG_GPIO=y added, and the LED name is slightly different on the Nitrogen board.

The code compiles and loads cleanly, but doesn't connect to an Android phone running the companion app. Any suggestions on how I should go about debugging this?

Thanks.

Would be nice to have the main.c as an attachment so it is easy to download. It would be more complete if you also state what software and their version you started with for the nRF52840 PDK ? I also assume you are using the 0.9.2 version of the nRF52840-PDK ?
