Data Sheet

Default firmware
PRBMD00 comes with default UART-BT firmware (firmware name: KATP), allowing user
able to enable their product with BT feature without any extra engineer resources. The
basic feature of KATP is to tunnel data between UART port Bluetooth device (Transparent
mode). User can develop their own firmware by SDK as well.
It also provides a AT-CMD mode for configuration:
Sending a test mode command in AT-CMD mode will force KATP to testing mode, which
allows user to fix the RF channel and power. Test mode is only for testing or certification
purpose only.
