Change the name of the node in the esp ble mesh

[abansal22]

Hello,

While building the esp ble mesh, the name of the node displayed while provisioning is displayed as the "ESP-BLE-MESH", I want to change the name to something else. Please let me know the procedure for that.

EDIT: Don't use this method, see my later reply.
The name is set in "components/bt/esp_ble_mesh/mesh_core/proxy_server.c", on line 1442:

Code: Select all

strncpy(device_name, "ESP-BLE-MESH", DEVICE_NAME_SIZE);

You can trace this back up to figure out an appropriate point to insert your own name, or simply replace this string.

OK since posting that earlier reply I've found a much better solution (even though it's old, putting it here for others with this issue), and it turns out there's just a function which wasn't in any of the documentation I had read called

Code: Select all

esp_bt_dev_set_device_name(const char* name)

which means you don't have to muck around with ESP-IDF's source code and can leave proxy_server.c alone. Call it after calling

Code: Select all

esp_bluedroid_enable()

. Makes sense there would be a function for it, just took me forever to actually find it!

Just wanted to point out that for the ESP32-C3, it can be done by

Code: Select all

bt_mesh_set_device_name(const char *name);
