Describe JBL-Pulse-2-Keep-disconnecting-from-Bluetooth here.

After searching the internet for the JBL sucky bluetooth and possible fix
1. The JBL gets confused with other Wifi/Bluetooth and struggle to work.
2. Try firmware upgrade
  1. Download android "JBL Portable"
  2. Move phone and speaker far away from any other 2.4GHz wifi/bluetooth, connect and check for firmware upgrade
  3. Firmware already on latest, seems JBL / Harmen is not releasing any fix.
    - 2021-12 "JBL Portalble" version: 5.3.66.5
    - Can have speaker read version with vol-down + connect button below it, hold for 3 sec.
    - Contact Harman Help Desk chat - They recommend, old, reset, try another phone, no firmware details, dont sell the model.
3. Reset speaker.
  - For 2 seconds, press and hold the "Volume +" and "Play" buttons. The JBL Pulse will power off and is now reset.
