It seems like there is little debate as to OTG helping to increase range. I don't yet have a controller or OTG cable, but am trying to get my head around the whole thing. This comes after reading a bunch on the web and watching a ton of videos. I headed down this rabbit hole after unsuccessfully trying to get my old Nexus 7 tablet to connetc to the Spark. My iPhone 6, iPad mini 2, and Google Pixl all connected fine. Turns out the Spark sometimes uses 5.8 GHZ for its wifi and the Nexus 7 only supports 2.4.
Anyway, back to my original question, why does OTG help with range?
My understanding of facts
- Remote Control will use 2.4 or 5.8 to communicate with the Spark. Whichever of these is not used is then available for the RC to Smart Device. The RC will essentially have two wifi connections, one to the Spark and the other to the device.
- 2.4 has a greater range than 5.8, but 5.8 has improved video streaming capabilities
- Some android devices can't use 5.8, such as my Nexus 7 and some Android devices in Europe are prevented from using certain 5.8 channel ID which means that they sometime fail to connect or even see the SSID or RC or Spark when flying without RC and connecting directly
My theroies as to why OTG improves range - all may apply?
- Since some android devices are unable to connect to the RC using 5.8 they hog the 2.4 for their needs leaving the lesser range 5.8 for the RC to Spark connection
- By using the OTG the smart device can be put into airplane mode, reducing local interference withthe wifi connection to the Spark form the RC
- Because the RC now nly has one active wifi conneciton to the Spark it also has no interference on this single connection
As an aside the wifi settings in the DJOGo app are only configuring wifi connecton with the Spark (between the RC and the Spark, or between the device and the spark when controlling with device alone). There is no way to configure the wifi between the RC and the smart device, correct? That conneciton wil just end up being whichever one the Spark is not using?
This is my first post here. I've been chatting a little on a Reddit board and a Facebook group for Spark owners. I like those since they are mobile phone friendly, but figured I'd try the official forum tonight. Any other good boards you guys use?
Thanks,
John
