how to send characteristic value to another nrf51DK board

[norin saiyed]

Hi, I'm using NRF51 DK board and i am following characteristic tutorial available. I am able to send temperature value over Bluetooth by using light blue app.. Instead of using this application now i want to send this data over Bluetooth to another nrf51 DK board.

Thanks

Then one of the boards must be Master (GAP Central) and second Slave (GAP Peripheral) In your case of LightBlu is your iPhone most probably Master so you need to achieve the same behavior in nRF5x FW to see the same. Have you ever run some nRF5 SDK examples against each other like Nordic BLE UART Service (NUS)? There are both Peripheral (+ GATT Server) and Central (+ GATT Client) examples in the SDK so I would start with them...
