Locating and disabling bluetooth on a JBL Flip Essential

If your JBL Flip 4 speaker refuses to connect to another device through Bluetooth, see the JBL Flip 4 Won’t Connect Through Bluetooth problem page for possible causes and solutions.

Problem solved. Bluetooth antennae located under passive driver with a sticker attaching it to the outer cylinder (labeled Flip 3 SE-V1). De-soldered sticker end, separated coaxial sheath from internal wire, attached 50-ohm resistor between the two (soldered) to create a circuit and hopefully absorb the signal. Wrapped resistor and wire in insulation tape, then wrapped all of it in aluminum foil (to allow it to earth/faraday) and then wrapped all of it in insulation tape and tucked it back in. The output signal is supposed to be 2.5 mW, it is now 10 to the -9 mW = minimal. Note device wouldn’t work until plugged in to charge, likely a battery sensor issue.
