If you encounter bluetooth errors when connecting to your beep base using the Android beep base app:
0x08 or OS code 8 --- "connection timeout" --- unable to connect to the beep base when selecting it in the beep base app
Hold your phone closer to the beep base circuit board (the bluetooth transmitter is located on the right-hand side of the enclosure when looking at the microphone plug) and reconnect.
0x13 or OS code 19 -- "connection closed by client" --- the beep base is not listed in the app after activating it with the magnet
Make sure there are no active bluetooth connections on your phone before you try to connect to the beep base. Disable your phone's bluetooth and close the beep base app. Now reopen the beep base app and when asked to
enable bluetooth, do so. The base should now be listed.
0x16 or OS code 22 -- "connection terminated by local host" --- unable to connect to the beep base when selecting it in the beep base app
"Un-pair" (or "forget") the paired beep base in your phone's bluetooth settings menu. Close the nRF Connect app if it is running in the background. Now close the beep base app and open it again. Reconnect to your beep base.
