PX4 / QGC Camera Trigger Issue – Image Capture Stops at Exactly 255 Photos

About the location I am. I am testing both Camera in Tanay Philippines. I am still using QGroundcontrol . About the usage of Siyi Unigcs app, Im still trying to review on how to use it since the terminology used in there is a bit different and Im looking for videos on youtube on how to use each modes in mission. also Im having a hard time in creating a waypoint or mission plan in Unigcs

Im still using the PX4 1.15.4 because there is no warning showing there like this . so Im waiting for it to disappear in the next stable version as 1.16.0 and 1.17.x still has this

I’d like to check: regarding the issue where only 255 photos can be taken, do you still need to wait for a PX4 update?

as of now still no progress. max image capture per flight is 256.

Our R&D team has provided an optimized test firmware to address the photo gray screen issue you reported. During outdoor flight tests, by integrating flight controller data and using MAVLink to control the camera, 500 photos were taken with no abnormalities detected. Please contact me via email at (fae05@siyi.biz), and I will send you the firmware for testing.

I need to correct a previously mentioned parameter related to the limit on the number of photos. The parameter provided by R&D is: CAM_TRIG_MAX_CNT. Could you please check again whether you have this parameter?
I made a mistake earlier, probably due to a translation issue. I’m very sorry.

what version of Px4 Firmware is this?
Currently im using px4 v1.15.4

this is the params I currently used on my drone

I cant see this CAM_TRIG_MAX_CNT in the param list. Do i need to enable this in boardconfig?
