NOTE:
Bluetooth mode: Does not work with Skysafari 7 Plus/Pro (...2023), only Wifi mode works.
(Something is wrong in this version. Perhaps now is working...)
Works fine (Bluetooth and Wifi) with Skysafari 5 Plus/Pro.
It is very likely to work with Skysafari 6 Plus/Pro
If you are owner of SkySafari 5 Plus and you cannot download the OBB file from its website (https://support.simulationcurriculum.com/hc/en-us/articles/115004749607-Data-Download-for-SkySafari-for-Android), here you can download it:

Here another DSC over ESP32-TTGO, a low cost development tft board.
Support WiFi ,Bluetooth and Serial (USB).
Skysafari, Ascom and Stellarium compatible.
Only support AS5600 sensor (x2):
Sensor 1: SCL1_PIN = 13 and SDA1_PIN = 15
Sensor 2: SCL2_PIN = 32 and SDA2_PIN = 33
Very important: I2C wires need additional 4K7 pullup (to Vcc) resistors if not in sensor board !!!
Sensor Vcc = 3.3V. Only four wires for each sensor (Vcc, GND, SCL and SDA)
Encoders system can downloaded from :

for Orion XT8: https://www.thingiverse.com/thing:4221923
for GSO 10": https://www.thingiverse.com/thing:4221918

13/02/2022 Be aware!!!!!
Some Power Banks generate electrical noise and interferes with I2C communication.
Keep it away from wires and controller (ESP32).
Keep low power: disable Wifi in configuration if you are going to use Bluetooth mode.
