BLE mesh sensor server model pararmeter settings

[sheldon123z]

Hi,

I am very confused about the sensor server model parameter setting. I have referenced the mesh model specification and tried to define a sensor model. However, I don't know how to set the states parameter in the esp_ble_mesh_sensor_srv_t and esp_ble_mesh_sensor_setup_srv_t, so I get errors when flashes the code to the board like this:

Code: Select all

E (1054) BLE_MESH: sensor_server_init, Invalid Sensor state parameter, model_id 0x1100
E (1054) BLE_MESH: sensor_server_init, Invalid parameter, model_id 0x1101

any help?

I'd also like to ask the same question. I've found where these errors are reported in sensor_server.c (see below) so it's clear that the sensor definition needs an array of esp_ble_mesh_sensor_state_t and each of these need a sensor_property_id, at least one state and a raw value. However, it's not clear how to configure these. For example "raw_value" in esp_ble_mesh_sensor_data_t is "struct net_buf_simple" so does it need to be created with the NET_BUF_SIMPLE macro and then initialised with "net_buf_simple_init". An example would be really useful.

Many Thanks

Bob
