Hi All,
My configuration:
- nrf52832 microcontroller
- Softdevice S132 V4.0.2
- Nordic SDK 13.0
I have problem with MacOS computer.
If I try to connect via BLE using a MacOS system, nrf52832 aborts connection and reboot automatically.
Instead, there are no problem if I connected to nrf52 with a windows system, android phone or iOS phone.
I'm using these values for GAP Configuration:
#define MIN_CONN_INTERVAL MSEC_TO_UNITS(15, UNIT_1_25_MS) #define MAX_CONN_INTERVAL MSEC_TO_UNITS(75, UNIT_1_25_MS)#define SLAVE_LATENCY 0 #define CONN_SUP_TIMEOUT MSEC_TO_UNITS(6000, UNIT_10_MS)
I'm using these values for Connection parameters:
#define FIRST_CONN_PARAMS_UPDATE_DELAY APP_TIMER_TICKS(5000) /**< Time from initiating event (connect or start of notification) to first time sd_ble_gap_conn_param_update is called (5 seconds). */#define NEXT_CONN_PARAMS_UPDATE_DELAY APP_TIMER_TICKS(30000) /**< Time between each call to sd_ble_gap_conn_param_update after the first call (30 seconds). */#define MAX_CONN_PARAMS_UPDATE_COUNT 3
static void conn_params_init(void){ uint32_t err_code; ble_conn_params_init_t cp_init;
memset(&cp_init, 0, sizeof(cp_init));
cp_init.p_conn_params = NULL; cp_init.first_conn_params_update_delay = FIRST_CONN_PARAMS_UPDATE_DELAY; cp_init.next_conn_params_update_delay = NEXT_CONN_PARAMS_UPDATE_DELAY; cp_init.max_conn_params_update_count = MAX_CONN_PARAMS_UPDATE_COUNT; cp_init.start_on_notify_cccd_handle = BLE_GATT_HANDLE_INVALID; cp_init.disconnect_on_fail = false; cp_init.evt_handler = on_conn_params_evt; cp_init.error_handler = conn_params_error_handler;
err_code = ble_conn_params_init(&cp_init); APP_ERROR_CHECK(err_code);}
Error occurs here:
case BLE_GATTS_EVT_EXCHANGE_MTU_REQUEST:err_code = sd_ble_gatts_exchange_mtu_reply(p_ble_evt->evt.gatts_evt.conn_handle, BLE_GATT_ATT_MTU_DEFAULT);APP_ERROR_CHECK(err_code); //NB: return error code = 8 break;
It returns error code n. 8.
Could you help me please?
Thanks
