Signal from your camera's hot shoe to both the Reach Module and Pixhawk

Hi, inkar.madikyzy

@inkar.madikyzy

Could you please share why you want to send the signals to both the Data logs and the Reach M2? The Reach M2 logs should already have all the necessary information for geotagging your photos.

In the case, when the method PPK not gives the good solution I wanted to use RTK/RTN.

You will understand the problem reading:

Until the use of my request - solution this in Emlid Studio [Geotag RTK/RTN images – Emlid Studio - #7 by kornel.nemeti] he needs: the hot shoe cable sends a signal from your camera’s hot shoe to both the Reach Module and Pixhawk. The signal adds time marks used for geotags to the Reach RINEX log file and the Pixhawk DataFlash log

Then, connect Reach M2 to Pixhawk using the appropriate telemetry port (usually TELEM2 or GPS2). I’m not familiar with the DataFlash logs, but from what I’ve seen on the ArduPilot forum, they include GPS time information. This includes data for all GPS instances, such as GPS week and milliseconds since the start of the week.

a) When using a hot-shoe, a “TRIG” message will be stored every time the flight controller commands a photo to be taken. A “CAM” message will be stored every time the flight controller receives a hot-shoe signal - indicating that the shutter was released. If the camera fails to take the picture, the “TRIG” message is recorded, but no “CAM” message is recorded.
b) When not using a hot-shoe, only “CAM” messages are stored. There are no “TRIG” messages. Without the hot-shoe input, a “CAM” message is stored every time the flight controller commands a photo to be taken. If the camera fails to take the picture, the “CAM” message is still stored

Without the gauge of the time in Pixhawk DataFlash the log I will not receive good, the quality of the data.
