Ok, with this hint I finally cracked it! The magic line in Arduino was to define the remote port as follows: unsigned int remoteport = udp.remotePort(); Though, the connection is not that stable? Aligning goes without problems, but long slews tend to cause hiccups. Any cures for this? I tried Indi and gphoto. Indi is complicated and gphoto does not really work with Sony cameras.

I got the app to send the :e1 to the mount and the mount replies =020401CR but after that, it's all silence. The SynScan Pro app just does not recongnize the reply? And I can't work out why.. And if I use serial instead of UDP over Wifi, the link works flawlessly. One possibility is that the Synscan Pro app listens a different UDP port than it's sending over. (Not 11880) I've used the roboremo esp32 code and tried modifying it with no luck. The plan is to use esp32 Wifi for the UDP-Serial link and bluetooth serial to control the camera shutter over manual release cable and optoisolators..

I also tested HC-12, a 433Mhz serial modem, cost about 5USD and the USB version a few dollars more. Works great and is 5V. If someone needs a longer range, this works up to a mile. Has someone gotten the Synscan Android or Windows app to work with the shutter release feature? It does not seem to work with HEQ5. What about the multi-purpose port on the Synscan handheld? My goal is remote shutter for a Sony A7..

I meant the DT-06.. Did it work out of the box after configuration? The ebay page says it's even 5V compatible.

Did you already get it working? I managed to find a code which supports UDP for ESP32 but the Android app just will not connect? https://github.com/roboremo/ESP8266-WiFi-UART-Bridge/blob/master/v1.1/sketch_esp_WiFi_UART_Bridge.ino

Is the software for this open source? Can someone find it? I didn't. Or is there another ESP32 compatible Wifi to serial bridge software which supports UDP? It could be flashed onto an ESP32 and be simply used with a level shifter.

Hello everybody! You can also easily make a bluetooth adapter and connect it directly to the Skywatcher Virtuoso mount without the Synscan handheld. Any bluetooth with TTL signals and 9600/ 8-N-1 will work. This works just fine. The difference between TTL and RS-232 is described here. If the bluetooth serial voltage is 3.3V, then the two resistors (voltage divider) will be needed. 47 ohm and 100 ohm is OK. 100 ohm goes between the bluetooth RX & GND. 47 ohm goes between Virtuoso TX and bluetooth RX. Otherwise the Virtuoso signal level is too high for the bluetooth 3.3V. Use the great Virtuoso app for Android, which works as a SkyFi emulator and link between your network and the star map software, such as SkySafari. Match the IP in Virtuoso app to Sky Safari SkyFi settings and leave the port as 4030. The LM2596 regulates the voltage from the Virtuoso battery to the bluetooth. You can also use a good old 5V regulator but I suspect it will waste power while lowering the voltage and transfering it to heat. Cut your grand-ma's phone cord and get her a cellphone, steal the RJ11 cable, solder the bluetooth and resistors and you're ready to go. Works as a charm. Tony
