Platform: CSR 8670

ADK: 3.5.1

Android Application: NRF Connect

I have created a custom service, and declared the read and write characteristic as follows:

primary_service {

uuid : 0xFFE1,


characteristic {

uuid : 0xFF01,

name : "DATA_READ",

flags : [ FLAG_IRQ ],

properties : [ read , notify ],

value : 0x0,


characteristic {

uuid : 0xFF02,

name : "DATA_WRITE",

flags : [FLAG_IRQ],

properties : [write_cmd]




While writing to the characteruistic 0xFF02 using Android application, I can only write once, after that I have to connect again to the device in order to write again. Is it the usual behaviour ? And also when I use write with response, nothing happens.


While using the flag FLAG_AUTH_W along with FLAG_IRQ, the applicaiton shows that the data is being sent multiple times but I can not read it on the device side.
