Thank you, Anas, for your reply. I agree you aren't there to support other hardware but you are there to support your own hardware such as the PXFmini whether it is being used with other hardware available from yourselves or others. It is also a forum so that users of your hardware can approach others with the same or similar hardware to gain insights.
My only complaint re the SK hardware comment is that a simple sentence in the documentation of the PXFmini such as "The PXFmini requires the use of ESCs using SimonK firmware such as our own (link to sales arm)." could have saved me a substantial amount of time and probably others too. However, every problem solved is a learning experience and as such I think I know more about the device now than I did before. A positive and one of the reasons why I went this way rather than just buy a ready made drone that works out of the box. As my wife says I always like to do things the hard way and things can be made too simple!
In addition you cannot assume that anybody interested in building a drone using your hardware is able to access it at the same price as somebody in Europe. I seem to remember when buying the PXFmini that the freight added more than 50% to the cost of the device. This is one reason why I am unlikely to buy the power module you sell despite the advantages, the same freight would more than double the cost of the module.
To your questions,
A good question, on the PC it is 2.0.24 on the PXFmini it seems to be the most up to date (cannot work out how to find out the version number - probably something easy). It is worth mentioning that I have never managed to get the USB connection to work through the Pi0 to my PC. Again, probably something simple to do with the setup of the Pi0
Looks like the videos are based on using an RC controller, not something I currently have but I have one coming (hopefully it will work with the PXFmini - I have attempted to get one with PPM output). I have been trying to get the thing working with a PC connected via wifi - the connection is ok as I get info back from the PXFmini regarding attitude and direction but have never managed to get the ESs calibrating/running. I will try again after viewing the videos.
mentioned earlier, yes I see the comment just feel there should be a short comment within the documentation of the PXFmini not just the purchase document for the ESCs.
I will download the parameter list and refer to the note though I think that once I have the SimonK ESCs installed it is more likely to be successful. Traps for the uninitiated.
Many thanks, again, the purchase of a power module will have to wait until I am next in Europe.
