Mavlink_Switch
ESP32 and ESP8266 only!
Mav2PT reads Mavlink telemetry from one of these sources
- Serial port or
- Bluetooth or
- WiFi or
- SD/TF Card
translates it to the FrSky DIY (passthrough) protocol and streams it through a serial port to S.Port/F.Port
In addition, it can then stream a Mavlink telemetry downlink to
- Serial port or
- Bluetooth or
- WiFi or
- WiFi and BT simultaneously and
- SD/TF Card
In config.h #define macros are used to select the FrSky port type.
If "No FrSky Port support needed" is selected, like the example below, then all the telemetry switching functionality remains, and Mav2PT becomes a configurable telemetry router or switch. All FrSky related settings are removed from the web interface.
// Choose either S.Port or F.Port or None
#define FrSky_Port_Type 0 // No FrSky Port support needed "Mavlink Switch"
//#define FrSky_Port_Type 1 // S.Port
//#define FrSky_Port_Type 2 // F.Port v1/v2 FrSky ISRM/ACCESS capable transmitters and receivers only
For all the uplink sources and downlink destination I/O types to become available for selection in the web interface, ensure that they are un-commented as below. This will make the relavent run time code available for selection in the web interface.

// NOTE: The Bluetooth class library uses a lot of application memory. During Compile/Flash

#define GCS_Mavlink_SD // SD Card - ESP32 only - mutually inclusive with GCS I/O
//#define FPort_To_SD // SD Card - ESP32 only - mutually inclusive with F.Port
The web interface will now look like this:
Setup the Uplink and downlink as required, save and reboot.
