• The pin
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 20 ms time-out
was detected or too much data was received via UART, the pin switches to HIGH and
data transmission starts via Bluetooth
®
LE. The pin switches LOW again, as soon as
Bluetooth
®
LE data transmission has finished. Then new data can be send from the host
to the radio module again. In case the pin is HIGH, no more data is accepted on the
UART.
