Hi There,
I want the functionality of my device to change when a value is written to a gatt characteristic. I've written an event handler that gets called whenever a write is made to the characteristic. This works correctly, but the problem is that I then can't get the value of the characteristic within this handler. I'm trying to use the sd_ble_gatts_value_get() function, and every time it is called the chip gets reset.
Thanks for any help you can give.
Here's my code:
void hex_evt_handler(ble_hex_t * p_hex, ble_hex_evt_t * p_ble_evt)
{
uint32_t err_code = NRF_SUCCESS;
uint8_t new_hex_status = 0;
uint16_t len = sizeof(uint8_t);
err_code = sd_ble_gatts_value_get(p_hex->hex_status_handles.value_handle,
0,
&len,
&new_hex_status);
if (err_code != NRF_SUCCESS)
{
return;
}
...
}
