Ble stack does not allow to write a read only type characteristic at Nordic Side

[adnan arshad]

Hi All,

In nRF52 SDK 15.3.0 , example ble_app_uart in peripheral mode, i have changed the TX characteristics which is initially of type (notify)  to type (read ). I am able to successfully  read the initial value assigned to characteristic in android side but stack does not allow me to update this characteristic in Nordic side. Kindly guide me how to update the value of a read only type characteristic at nordic side.

Kind regards

Why not? What happens? What are you doing to update the value?

[adnan arshad]

When i try to update the characteristic in function nus_data_handler(ble_nus_evt_t * p_evt) on receiviing interrupt of ble then stack crashes with kit reset.

How does it crash? Does it give an error? What error? And where?

When i enable notify then it allows me to update the value of characteristic but not with ready type only.

What are you doing to update the value?

What does that mean? Can you show some code?
