characteristic write operation

[mohBOSS]

Hi all,

how can I retrieve characteristic's value after write operation to this characteristic ?

can I use it as soon as it is modified ?

Thanks !

You shouldn't need a timer to check the value of a characteristic. If the characteristic is write enabled you should get a BLE_GATTS_EVT_WRITE event every time it is written to. You can then check the handle in the event to make sure it matches your characteristic and read the value out of the characteristic.

I pull the data out of a written characteristic from here: p_evt_write->data[0]
