5.9.17.2 Port Configuration for UART
Message
UBX-CFG-PRT
Description
Port Configuration for UART
Firmware
Supported on:
• u-blox 9 with protocol version 27
Type
Get/Set
Comment
This message is deprecated in protocol versions greater than 23.01. Use UBX-CFG-
VALSET, UBX-CFG-VALGET, UBX-CFG-VALDEL instead.
See the Legacy UBX Message Fields Reference for the corresponding configuration item.
Several configurations can be concatenated to one input message. In this case the payload
length can be a multiple of the normal length (see the other versions of CFG-PRT). Output
messages from the module contain only one configuration unit.
Note that this message can affect baud rate and other transmission parameters. Because
there may be messages queued for transmission there may be uncertainty about which
protocol applies to such messages. In addition a message currently in transmission may be
corrupted by a protocol change. Host data reception parameters may have to be changed
to be able to receive future messages, including the acknowledge message resulting from
the CFG-PRT message.

Payload Contents:
Byte Offset Number
Format
Scaling Name Unit Description
0 U1 - portID - Port Identifier Number (see Integration Manual
for valid UART port IDs)
1 U1 - reserved1 - Reserved
2 X2 - txReady - TX ready PIN configuration (see graphic below)
4 X4 - mode - A bit mask describing the UART mode (see
graphic below)
8 U4 - baudRate Bits/s Baud rate in bits/second
12 X2 - inProtoMask - A mask describing which input protocols are
active.
Each bit of this mask is used for a protocol.
Through that, multiple protocols can be defined
on a single port. (see graphic below)
14 X2 - outProtoMask - A mask describing which output protocols are
active.
Each bit of this mask is used for a protocol.
Through that, multiple protocols can be defined
on a single port. (see graphic below)
16 X2 - flags - Flags bit mask (see graphic below)
18 U1[2] - reserved2 - Reserved
