  1. I am on to something. I think the "Doit" firmware that is installed on the dt-06 chip is introducing the delays. Unfortunately the code for the firmware is not available anywhere. I have compiled a simpler version of a UART bridge code with a small buffer for the UDP packet transmission to the serial port and i have impressive response times in the Synscan Mobile App. All the attempts have a response time <50 ms.!! while with the Doit firmware i average at 200ms. this is still in development before i do the final wiring and soldering and coding! The test i did is based on https://github.com/roboremo/ESP8266-WiFi-UART-Bridge that was mentioned earlier in the thread. (i will not go into how to build/install etc. esp8285 chips) https://github.com/roboremo/ESP8266-WiFi-UART-Bridge/blob/master/v1.1/sketch_esp_WiFi_UART_Bridge.ino I did a couple of fixes in the code to make it work before burning it to the ESP chip change the port to 11880 chose the UDP defines in the code changed the buffersize to 4096 (but original should work too although prob less efficient) corrected udp.beginPacket(remoteIp, port); // remote IP and port to udp.beginPacket(remoteIp, udp.remotePort()); // remote IP and port my next step is to find ways to make the STA/AP modes configurable via web interface as well as other params (like buffersize). will keep the group posted.
  2. hi thanks for the response. 1) i use APT goto++ and that works fine with Wifi with the adapter. not yet fully convinced of the Autoguiding though in that mode given we need some low latency for that. 2) however in the 2 (or 3) star alignment process (before launching APT!) then the arrow buttons (HW or SW) via the minipc still cause this troubling latency that as use say make it unusable. Alignment is key for me since i need it to perform the polar alignement fine-tuning via the synscan app. Again quite different from the original SkyW module. 3) regarding AP mode i believe that it is only operational if the TCP server is on. So if we have UDP on 11880 then that mus disable the AP mode of the DOIT firmware. Maybe there is a better Firmware out there that can keep both services up (tasmota?) and still work on the serial - wifi 4) alas i found a workaround to set my miniPC as a hosted network (by loading win 8 wifi adapter drivers on it!) making point 3) above less of an issue...
  3. 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
