Hi to all,
I am using smart RF06 development board to program simple ble peripheral project.when i run it, "advertising" is displayed on LCD but when i enable the Bluetooth in a smart phone the name is not being displayed in smart phone what could be reason.any help appreciated.
Below attached is the simpleblepheripheral.c file
