Hi,
I am currently writing a mobile application with Capacitor framework and I need the app and a node in a ESP-BLE mesh to share data. To do this, I have the idea of creating 2 GATT services on the BLE mesh node; 1 for receiving another 1 for transmitting.
When I scan the BLE node using the app, I see that it has 1 service used for the mesh advertising. How can I add another custom GATT service?
Thank you for your time.

I do not know about which BLE framework, lets say esp's own(bluedroid) or NimBLE port for ESP32 you are using.?
But Nimble also supports mesh network. For that you need to define a struct containing services and characteristics. Then you should have callbacks for those BLE GATT/GAP events. This is the normal flow...

Code: Select all
static const struct ble_gatt_svc_def gatt_svr_svcs[] = {
{
.type = BLE_GATT_SVC_TYPE_PRIMARY,
.uuid = &gatt_server_service_uuid.u,
.characteristics = (struct ble_gatt_chr_def[]){ {
.uuid = &gatt_server_f_characteristic_uuid.u,
.flags = BLE_GATT_CHR_F_WRITE | BLE_GATT_CHR_F_READ,
.access_cb = gatt_callback
//.val_handle = &gatt_svr_chr_val_handle,
}, {
.uuid = &gatt_server_s_characteristic_uuid.u,
.flags = BLE_GATT_CHR_F_WRITE | BLE_GATT_CHR_F_READ,
.access_cb = gatt_callback
//.val_handle = &gatt_svr_chr_val_handle,

.uuid = &gatt_server_t_characteristic_uuid.u,
.flags = BLE_GATT_CHR_F_WRITE | BLE_GATT_CHR_F_READ,
.access_cb = gatt_callback
//.val_handle = &gatt_svr_chr_val_handle,
}, {
0,
},
}
},
{
0,
},
};

Thanks for the reply.
I am using the ESP-BLE-MESH library with NimBLE stack.
The confusing part for me is how to register those GATT services when setting the ESP32 as a BLE Mesh node since the initialization of the GATT server and registering of services is handled internally by the BLE-MESH library code. Hence, I do not have a pointer to the GATT server to register custom services.
