USING THE PERIPHERAL_UART TO CONNECT WITH THE MULTIPLE CENTRAL DEVICES . I MODIFIED SOME CODE AND ADDED THE CUSTOM DATA WHICH IS HAVING THE 5 BYTES. WHEN I USE TO FLASH THE CODE THE BOARD IS AUTOMATICALLY RESETTING WHETHER THE DEVICE IS CONNECTED NOR CONNECTED . BELOW I PROVIDE THE LOGS :

LATER THE RESETTING THE BOARD IT IS SHOWING THE 35 , 12 etc,. MESSAGES DROPPED .

The Application just keep looping around.
Hope for your valuable suggestions to overcome from this .
Thank you in Advance.
