service was not found at the peer with error BLE_DB_DISCOVERY_SRV_NOT_FOUND

Hi everyone,

I am developing a remote controller using nRF52832 chip. My prototype is currently developed in PC10040 board. The IDE is Eclipse Oxygen, and the SDK is S132 v5.0.0.

Currently, I am trying to get data from a Google Daydream controller. It has a service with UUID 0xFE55. I can successfully connect to the device. The problem is that when the nRF52832 try to discover database it return BLE_DB_DISCOVERY_SRV_NOT_FOUND :((( I don't know where is the mistake I made.

Could you give me an advice please?

Hi Sigurd, I made a mistake that I forgot changing the type of the scanning UUID. Now I can discover the service. The nRF52832 chip is a central deivce and the daydream remote controller is a peripheral. So now, I have a new challenge: receiving data from a peripheral using BLE central device. I take a look at the central tutorial and it tells me that I have to turn on the notification using ble_nus_c_rx_notif_enable(). But when I search in ble_app_uart example, there is only ble_nus_c_tx_notif_enable??

How can we change the type of the scanning UUID?

Hi User1321,

If the scanner receives an advertising report, you will get the event BLE_GAP_EVT_ADV_REPORT. In the ble_app_uart_c example, the function on_adv_report() and ble_advdata_uuid_find() is then called. If the m_nus_uuid (defined in main.c ) is not found in the advertising packet, the central will not connect.
