• The pin BUSY can be used as a kind of flow control for the data transmission during
the peripheral only mode. By default the pin level is LOW. As soon as the 20ms timeout
was detected or too much data was received via UART, the pin switches to HIGH and
data transmission starts via Bluetooth
®
Bluetooth LE data transmission has finished and the transmission of new data is feasible
again. In case the pin is HIGH, no more data is accepted on the UART.

To use the signal on the BUSY pin as flow control on the host controller side, we recommend
to use an OR gate to combine the /RTS and BUSY pins' signals.
