hi. thanks for the detailed instructions. this is a great post!
I have followed everything to the letter and also acquired some basic soldering skills thanks to this post. I have to report success! (using the buck converter)
However i am not 100% there. few issues i would like to share to see if i am alone:
1) there is some lag/delay in the commands. I use a joystick with ascom/synscan app on my pc or when i connect with the synscan app on my iphone. Fine tuning position becomes really difficult as there is a unclear amount of delay between a button press and a reaction from the mount (HEQ5) with the home made adapter. I dont have this delay when in serial cable and i did not have the delay when i used the official Synscan Wifi adapter that i lost hence i tried this route. I tried to change the various timeout settings but nothing really made it close to the old setup. For info the diagnostics function in the synscan advanced menu gives me good results with responses of less than 200ms.
2) i would like to use the adapter in remote site mode as my central AP to connect all my gear (mini pc, mount, and camera (yes it is over wifi) and control PC with remote desktop. however when connecting to the Doit (or any renamed AP) devices can connect to the DOIT network but they cannot talk to one another. I cannot ping any device, cannot discover any IP address on the wifi network and for sure cannot remote remote desktop into my minipc. this is rather annoying as this was a setup i could achieve with the original Skywatcher adapter and my minipc cannot act as a hotspot thanks to Win10.!
Anyone sharing the same limitations?
Thanks
