## CalTopo / SARTopo
|
|
|
|
Meshtastic can integrate with [CalTopo](https://caltopo.com/) Desktop edition quite easily through the product's APRS over serial support.
|
|
|
|
### Configuring the Meshtastic device
|
|
|
|
To configure our Meshtastic device for this integration, we have a couple of different options, both of which utilize the [Serial module](/docs/settings/moduleconfig/serial):
|
|
|
|
#### Enabling serial over the device's USB port
|
|
```shell title="Serial over USB"
|
|
meshtastic --set serial.enabled true --set serial.baud BAUD_9600 --set serial.mode CALTOPO --set serial.override_console_serial_port true
|
|
```
|
|
|
|
#### Enabling serial over an external USB to Serial adapter
|
|
```shell title="External serial adapter"
|
|
meshtastic --set serial.enabled true --set serial.baud BAUD_9600 --set serial.mode CALTOPO --set serial.txd = 13 --set serial.rxd = 14
|
|
```
|
|
|
|
:::info
|
|
Ensure that serial baud rate is set to `9600` on both the Meshtastic device and the CalTopo / SARTopo `topo.properties` configuration

### Setting up CalTopo / SARTopo

|
|
|
To setup CalTopo for Meshtastic integration using the Live Tracking via APRS, refer to the official [documentation](https://training.caltopo.com/all_users/share/live-tracking#aprs).

Example `topo.properties` file configuration for use with Meshtastic:
