Cannot get notifications data on BLE_NUS_C_EVT_NUS_RX_EVT

[Vitaliy]

Hi,

I am trying to change an example code on ble_app_uart_c (Central) SDK10.0.0 s130.

I have changed already peripheral example and I can see notification data if I connect to peripheral (ble_app_uart) via IOS LightBlue app.

But I could not get the same data via Central example, what I am missing?

Peripheral sends 20bytes via ble_nus_string_send after check:

if (p_ble_evt->evt.gatts_evt.params.write.handle == m_nus.rx_handles.cccd_handle) {

From Central I can see only:

Connected to target
[DB]: Starting discovery of service with UUID 0x1 for Connection handle 0
[DB]: Discovery of service with UUID 0x1 completed with success for Connectionhandle 0
The device has the device RX characteristic
The device has the device TX characteristic

Any help would be greatly appreciated.

I changed only SCAN_WINDOW and made it the same as SCAN_INTERVAL.

Now I realize that Central actually receives sometimes data from Peripheral but not always:

The device has the device TX characteristic
p_ble_evt : 55
p_ble_evt : 56
Received RX_EVT
0123456@ABC`p_ble_evt : 56

Maybe there is nothing wrong with Central but with Peripheral...?

Peripheral side transfers 20 bytes data after it receives the event:

case BLE_GATTS_EVT_WRITE:						
`if (p_ble_evt->evt.gatts_evt.params.write.handle == m_nus.rx_handles.cccd_handle) {
#sending 20 bytes of data
   ble_nus_string_send(&m_nus, data_array, data_size);
   sd_ble_gap_disconnect(m_conn_handle,BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION);
}`
