Main Logic Board Assembly
The Bluetooth transceiver and the NVRAM (Non-Volatile Random Access Memory) are integrated into the primary PCB. Pairing failures occur when the pairing table stored in flash memory becomes corrupted or the Bluetooth IC fails to enter the 'advertising' state due to a breakdown in the Frequency Hopping Spread Spectrum (FHSS) timing crystal. Replacing the board ensures a clean firmware state and a functional radio module.

Button Control UI Flex Cable
To initiate pairing, the user must actuate the Bluetooth button which sends a specific voltage drop signal to the MCU. If the flexible ribbon cable connecting the top-mounted buttons to the main logic board develops micro-fractures in the copper traces due to mechanical stress or thermal cycling, the 'Pairing Mode' command is never received by the processor, rendering the device invisible to host controllers.

Replacement Li-ion Battery
Bluetooth discovery and handshake protocols require momentary peaks in current draw from the power management integrated circuit (PMIC). If the internal battery has high internal resistance or chemical degradation, the voltage can sag below the operational threshold for the radio module during the pairing handshake, causing the process to fail or time out before the secure simple pairing (SSP) is completed.
