Hello ,
I have configured one nrf52832 where it sends temperature data over one service's characteristics ( updating the value after every 1 min ) and I am able to see this by connecting it to nrf connect mobile app . I have also configured one more nrf52832 device in central mode , where it connects to my first device ( it discovers the device using service UUID filters and then connects ) it has to read the connected device's temperature via sd_ble_gattc_read () function .
Now the issue is , during configuration of the characteristics , I have given add_char_params.p_init_value as some static value ( 0xab ) . and from my central device , I am reading the device temperature after every 2 mins ( after 2 min I will connect and read the UUID ) , but I am getting 0xab ( init value only) always ( not able to read the updated value ) .
I have also tried removing the init value configuration , but with this, always I get 0xB1 ( unknown value ) .
this is how I am reading from my central device :
sd_ble_gattc_read(p_ble_evt->evt.gattc_evt.conn_handle, UUID_TEMP_HANDLE_VAL, 0));
( this im calling whenever the central device connects my second device and discovers the UUID )
and in the ble_cental_handler ,
case BLE_GATTC_EVT_READ_RSP:
{
NRF_LOG_INFO("Data : %x :\n",p_ble_evt->evt.gattc_evt.params.read_rsp.data[0]) ; // here I am getting init value always
NRF_LOG_INFO("len : %x :\n",p_ble_evt->evt.gattc_evt.params.read_rsp.len) ;
NRF_LOG_INFO("handle vlaue : %x :\n",p_ble_evt->evt.gattc_evt.params.read_rsp.handle) ;
NRF_LOG_INFO("offset : %x :\n",p_ble_evt->evt.gattc_evt.params.read_rsp.offset) ;
}
break ;
How do I resolve the issue ??
