Hello,
I'm getting err_code BLE_CONN_HANDLE_INVALID after calling ble_cps_measurement_send
I thought ble_cps_on_ble_evt was handling all of this but seems not.
I tried adding this line :
NRF_SDH_BLE_OBSERVER(m_cps_obs, APP_BLE_OBSERVER_PRIO, ble_cps_on_ble_evt, &m_cps);
in ble_stack_init() but it didn't work
I tried passing the connection handler in the ble_evt_handler but now it wont advertise
static void ble_evt_handler(ble_evt_t const * p_ble_evt, void * p_context)
{
ret_code_t err_code = NRF_SUCCESS;
switch (p_ble_evt->header.evt_id)
{
case BLE_GAP_EVT_CONNECTED:
NRF_LOG_INFO("Connected");
err_code = bsp_indication_set(BSP_INDICATE_CONNECTED);
APP_ERROR_CHECK(err_code);
m_conn_handle = p_ble_evt->evt.gap_evt.conn_handle;
m_cps.conn_handle = m_conn_handle;
err_code = nrf_ble_qwr_conn_handle_assign(&m_qwr, m_conn_handle);
APP_ERROR_CHECK(err_code);
break;
...
}
And so many other things which all doesn't work...
Looking for help
here's the main :
