Discover service always got error : BLE_GATT_STATUS_ATTERR_ATTRIBUTE_NOT_FOUND

[bob]

Hi, I am using S120 1.0.0 and SDK 6.0.0. Learning the sample project 'ble_app_multilink_central'.

I already got a peripheral device with NUS service. The central device can connect the peripheral device, but when discovering peripheral service, I got error BLE_GATT_STATUS_ATTERR_ATTRIBUTE_NOT_FOUND in on_primary_srv_discovery_rsp.

What can I do to discover the NUS service and all other services ?

You can use the database discovery module to do service discovery.

It is described in the SDK documentation here.

I recommend you to examine ble_app_hrs and ble_app_hrs_c first, and then modify this to ble_app_uart. I have tried to explain how the database discovery module works in ble_app_hrs_c in this question.

It is very difficult to give you a specific answer, because you are only giving us the response. You say nothing about what your attribute table actually looks like, or what you have as arguments to sd_ble_gattc_primary_services_discover()
