Hi.

[quote user="Liaokeyun"]feeling confused about Mesh-based provisioning bearer.[/quote]

NRF_MESH_PROV_BEARER_MESH - Mesh-based provisioning bearer:

This bearer is defined for the internal use to identify the correct bearer instance that should be used by stack when remote provisioning process is started.

See:
examples\pb_remote\client\src\main.c: Line 323

models\experimental\pb_remote\src\pb_remote_client.c: Line 1087

Best regards,
Joakim

Hi Joakim，I am not still able to get PB-GATT clear, I have seen three definition in the struct nrf_mesh_prov_bearer_type_t within nrf_mesh_prov_bearer.h resulting in feeling confused about Mesh-based provisioning bearer. Thanks for your effective reply!

Hi.

The Bearer Layer defines how PDUs are transported between nodes using an underlying Bluetooth Low Energy stack. Currently, two bearers are defined, the Advertising Bearer and the GATT Bearer.

PB-ADV is used for provisioning devices within radio range of the provisioner.

PB-GATT is used for provisioning mesh devices by (legacy) devices that only support the GATT bearer.

Best regards,
Joakim
