How to change Bluetooth device name on UP2STREAM PRO V4?

Device Information:

  • Model: UP2STREAM PRO V4
  • Hardware: A31
  • Firmware: 4.6.415145 (2022-04-27)

Issue:
My device’s Bluetooth name is showing as “{{USER}}” and I need to change it to a custom name.

I’ve tried using setDeviceName via the HTTP API, but it only changes the WiFi/UPnP/DLNA name, not the Bluetooth name.

Question:
Is there an HTTP API command or other method to change the Bluetooth device name?

Thank you!
