## Serial port functions and scenarios
|
|
|
|
### Serial port scenarios
|
|
|
|
```
|
|
0 UNUSED
|
|
1 MSP, CLI, TELEMETRY, GPS-PASTHROUGH
|
|
2 GPS ONLY
|
|
3 SERIAL-RX ONLY
|
|
4 TELEMETRY ONLY
|
|
5 MSP, CLI, GPS-PASTHROUGH
|
|
6 CLI ONLY
|
|
7 GPS-PASSTHROUGH ONLY
|
|
8 MSP ONLY
|
|
```
|
|
|
|
### Contraints
|
|
|
|
* There must always be a port available to use for MSP
|
|
* There must always be a port available to use for CLI
|
|
* To use a port for a function, the function's corresponding feature must be enabled first.
|
|
e.g. to use GPS enable the GPS feature.
|
|
* If the configuration is invalid the serial port configuration will reset to it's defaults and features may be disabled.
|
|
|
|
### Examples
|
|
|
|
All examples assume default configuration (via cli `defaults` command)
|
|
|
|
a) GPS and TELEMETRY (when armed)
|
|
|
|
- TELEMETRY,MSP,CLI,GPS PASSTHROUGH on UART1
|
|
- GPS on UART2
|
|
|
|
```
|
|
feature TELEMETRY
|
|
feature GPS
|
|
save
|
|
```
|
|
|
|
b) SERIAL_RX and TELEMETRY (when armed)
|
|
|
|
- TELEMETRY,MSP,CLI,GPS PASSTHROUGH on UART1
|
|
- SERIAL_RX on UART2
|
|
|
|
```
|
|
feature -PARALLEL_PWM
|
|
feature TELEMETRY
|
|
feature SERIAL_RX
|
|
set serial_port_2_scenario = 3
|
|
save
|
|
```
|
|
|
|
c) GPS and TELEMETRY via softserial
|
|
|
|
- TELEMETRY,MSP,CLI,GPS PASSTHROUGH on UART1
|
|
- GPS on UART2
|
|
|
|
```
|
|
feature -PARALLEL_PWM
|
|
feature PPM
|
|
feature TELEMETRY
|
|
feature GPS
|
|
feature SOFTSERIAL
|
|
set serial_port_3_scenario = 4
|
|
save
|
|
```
|
|
d) SERIAL_RX, GPS and TELEMETRY (when armed) MSP/CLI via softserial
|
|
|
|
- GPS on UART1
|
|
- SERIAL RX on UART2
|
|
- TELEMETRY,MSP,CLI,GPS PASSTHROUGH on SOFTSERIAL1
|
|
|
|
```
|
|
feature -PARALLEL_PWM
|
|
feature TELEMETRY
|
|
feature GPS
|
|
feature SERIALRX
|
|
feature SOFTSERIAL
|
|
set serial_port_1_scenario = 2
|
|
set serial_port_2_scenario = 3
|
|
set serial_port_3_scenario = 1
|
|
set msp_baudrate = 19200
|
|
set cli_baudrate = 19200
|
|
set gps_passthrough_baudrate = 19200
|
|
save
|
|
```
