Hi Dialog Team,
I have one handler function for the four characteristics which are used to turn on LEDs . Each characteristic should turn on only one LED . However, each characteristic can turn on all the 4 LEDs. I have used one handler function for all the four characteristics.
a) Should i use seperate handler functions?
b) Is there any way to differenciate between the data that i am writing in characteristics from one another.
I just want to check, in which characteristic the user inputs data and accordingly turn the LEDs on/off.
I am eagerly waiting for a reply.

Hello Sam123,
1)Do you know the value of your AD converter result register (register is called GP_ADC_RESULT_REG)? Is it different to what you see in BlueLoupe? Do you read the register with GetWord16, not GetWord8/GetByte?
2)You only need one handler function for write. For example, if you open acceleration profilesaccel_task.c, you can find handler function
static int gattc_write_cmd_ind_handler. There the handling of different characteristic value attributes is managed with switch --- case statement:Hi,
I have four characteristics which should turn on four different LEDs. Each characteristic should switch ON/OFF the LED assigned to its characteristic. However each characteristic can switch on/off all the 4 LEDs. There should be a switch case to differenciate between the characteristics so that writing to characteristic 1 will only turn on LED1 and not LED2/LED3/LED4. I am uncertain about the switch condition and the switch cases that should be implemented. I am attaching my handler function for your kind perusal. How to implement the switch case statement?
