WIFI VS BLUETOOTH CONTROLLER SERIAL

While the serial data is essentially identical, the electrical signal formats differ. Note that some telescopes may also contain a TTL serial data connection port. Considering the issues outlined above, it is fairly obvious that most of the consumer grade telescope mounts today contain an RS232 serial data port.

They are (1), understanding the above listed wireless communication limitations, and (2), providing telescope control software that supports RS232 serial data connections. There are two primary factors involved in establishing wireless telescope control. Most newer Windows and Mac OS-X computer operating systems, along with computers containing a Bluetooth adapter, are able to provide wireless Bluetooth serial data connections supporting the SPP protocol.The Apple iOS operating system does not support the Bluetooth SPP protocol which eliminates a generic Bluetooth solution using Apple tablets and Smartphones.

As in the case above, most Android devices can only connect using the WiFi infrastructure mode.

The Celestron SkyQ WiFi adapter is primarily limited to Celestron models that contain an AUX/HC port since it provides a TTL serial data connection (as opposed to RS232 serial data) to the telescope mount.

This adapter currently sells for $159.95. Apple iOS, Windows and Mac OS-X operating systems can establish both infrastructure and direct Ad-Hoc WiFi connections.

The popular Sky Safari “SkyFi” adapter employing WiFi connectivity, while perhaps the most versatile approach, limits most Android devices to connect using the Infrastructure WiFi connection mode (WiFi Ad Hoc direct connection is typically not supported).

While there are wireless telescope control solutions available, they tend to bring a degree of limitations with them. The device described below was designed to provide both WiFi and Bluetooth telescope control over a wireless link using a tablet, Smartphone or laptop computer. Both WiFi and Bluetooth wireless control are available for use in establishing a wireless serial data link to a telescope that contains a standard RS232 serial data interface. With the introduction of tablet computers and Smartphones running Apple’s iOS and Google’s Android operating systems, there’s no longer a need to use a bulky laptop computer to remotely control a GoTo telescope. Reduced cord wrap and the number of interconnecting cables, not to mention the effort required to view a hand controller’s tiny display in the dark are two advantages. Wireless control of a typical consumer grade GoTo telescope provides several advantages.
