UART configuration
The Development Dongle v1.0 UART lines are connected to pins P0.00 to P0.03 as shown in
Table 4
Development Dongle v1.0 UART configuration
The Development Dongle v2.0 UART lines are connected to pins P0.08 to P0.11 as shown in
Table 5
nRF51822 Development Dongle UART configuration
Note:
The UART signals are routed directly to the SEGGER chip. The pins should only be used for
UART. In order to use the USB to UART bridge, the software on the nRF51822 has to enable
flow control. For details on how to set up the UART with flow control, see the
nRF51 Series
