Monitored network traffic with Wireshark. All I can see that the app is trying to reach the DT on 11880 and nothing more. I think I just stop experimenting with it before I kill the motor controller. Thanks R26 Oldtimer for the helping hand, clear skies!

Good question, try to find it. Although, I think the communication on data lines would be the next step after the conneciton btw. dt and the app has been estabilished - or am I wrong? Thanks EDIT: by googling found that eq3 uses probably 5V TTL level. On the other hand, I just saw the circuit of a Synscan Wifi. It is an ESP-WROOM-02, and a STM32 microcontroller. The ESP communicates on 3.3V and on the board I couldn't find components of a shifter, thus the motor controller should also communicate on 3.3V.

Tried with motors connected - nothing. My next (and maybe last) idea is to monitor the connection with wireshark, to see where the connection gets dropped. Interesting, if I check open ports with the Fing app only port 80 seems to be open.

Increased voltage on 5V, unfortunately still the same story. The blue LED on the board is flashing fast as I push the <Connecting> button in the app (where the SSID of the DT appears correctly) but there's still a "Cannot Connect" message. This flashing tells me at least, the device and the DT try to communicate with each other. The next, I'd give a try is to connect the motors as read somewhere as solution (even if I don't think, for a WIFI connection this shouls be a bottleneck). Endless debuging... 💩

and there's the point. I checked the DT-06's data sheet and 4.5-6V is the necessary power supply, so 3.3V isn't enough for it clearly. Stupid mistake 🤬, I confused it with another running project of mine, that this DC buck converter was originally for, only after I dropped the handheld and the LCD was broken, this Synscan wifi obviously overtook it. I checked everything for hours, for this I may never realize that it needs more power. I'll try it in the evening. The other settings were as shown in the pictures. Thanks for the idea. 👏

Hi stargazers, I need help with the DT-06 connection. I built the adapter based on the description here (my mount is a EQ3 goto, so I modified the wiring accordingly). The module receives 3.3 V on a DC buck converter. I made the settings, connect to the adapter at 192.168.4.1, can manage it, but Synscan App Pro can't connect to it, the error message is always "cannot connect". I tried under iOS, Android, Windows, I get the same error message everywhere. Using Fing to discover the connection can see, that DT-06 and Phone (or PC) are in the same VLAN on Wifi (DT has 192.168.4.1, device gets 192.168.4.2). I only use the motor controller for the connection test without the motors (no RA and Dec cables connected), but I don't think that would affect the connection. Does anyone have an idea what could be wrong? Thanks: Frigyes
