Audio data from the microphone is captured and LED data is sent over the Raspberry Pi serial ports. This data is sent and received at a custom baud rate of 250KHz, hence the serial port baud rate is set via /boot/config.txt:
Although these settings are documented as only affecting the secondary, mini uart port, they seem to disable Bluetooth.
After the pi-topPULSE is disconnected, these settings are not restored to their defaults, so the pi-topPULSE can be reconnected and used without rebooting.
Workaround
For the time being, it is possible to restore Bluetooth functionality after using a pi-topPULSE by manually commenting out these settings in /boot/config.txt.
Disconnect the pi-topPULSE. If a pi-topPULSE is connected, serial device settings will be restored automatically.
In a terminal window run the following: sudo leafpad /boot/config.txt
Find the following lines:
init_uart_clock=1627604
init_uart_baud=460800
Comment them out by adding a # symbol in front of each:
#init_uart_clock=1627604
#init_uart_baud=460800
Save the file
Reboot your Pi
