How to read a characteristic value?

Hi Sandeep

When notifications are disabled you won't be able to send notifications.

If you use the sd_ble_gatts_value_set(..) function instead it should work. This will change the value of the local attribute, and once you read it from the app the updated value should be reflected.

Hi ovrebekk thanks for the reply,

Yes after disabling the notification from the app when i do a read request, it shows me the value that i had used while initializing the characteristic.

for ex:

value=2;

add_char_params.p_value=&value;

i increment the "value" for every notification interval. After stopping the notification interval when i hit read, i get the output as 2 only.

Hi Sandeep

What issue are you seeing?

Are you reading something other than 5 after disabling notifications in the app?
