Main PCBA (Logic Board)
The Bluetooth transceiver and its associated firmware are integrated directly onto the main printed circuit board assembly. A hardware failure in the 2.4GHz radio or a corruption of the onboard flash memory responsible for the Bluetooth stack prevents the device from broadcasting its SSID or completing the secure handshake. Replacing the board restores the communication protocol hardware.

USB-B to USB-A Firmware Cable
Connectivity failures in the Spark 40 are frequently software-bound rather than mechanical. Since the Bluetooth module cannot be updated wirelessly when pairing fails, a physical USB connection to a PC/Mac is required to re-flash the system firmware, which resets the Bluetooth stack's state machine and clears pairing cache errors.

Internal Bluetooth Antenna
The internal PCB antenna is connected via a small U.FL or soldered coaxial lead. Mechanical vibration from the amplifier's speakers can occasionally loosen or detach this lead, significantly reducing the signal-to-noise ratio and preventing successful pairing despite the module being active.
