I was having a few intermittent connection issues that made me a little nervous so I purchased an OTG cable through Amazon. I tried using the cable on several devices as my goal was to dedicate an old tablet to the Spark. It turns out that not every Android device supports OTG and there is an app available in the Play Store to determine how your device will behave (USB Host Diagnostics). My tablets were too old, but I was able to connect to an old Samsung S5 Galaxy phone. The performance difference was remarkable and I was very happy. However, for reasons I can't fathom, I started getting a tremendous lag in video signal, so much that I couldn't fly the Spark. I had several sessions with DJI Support and they asked my to return the Spark for evaluation - I declined while I tried to find the source of the problem. Last night I upgraded FW for both the Spark and Remote Control and now there is no lag whatsoever. In fact, I can now fly the Spark further then ever without a single warning of week transmission (3100 ft at 250 ft elevation).
I have learned that the order of making connections is important with the OTG cable. I turn on the RC, then start the Android DJI GO 4 app, then connect the cable to the phone, and finally connect the OTG adapter or cable end to the Remote Control (there are pins shorted in the OTG adapter and it's important that it be plugged into the RC and not the display device).
Thank you for posting your instructions. I can now confirm this is the exact same method that is required for iOS. I could not get OTG working yesterday after doing the firmware upgrade and restarting both devices. Following your instructions, OTG connected immediately.
iOS OTG Steps -> Power on Remote -> Power on Spark -> Launch DJI GO -> Connect OTG to iOS Device -> Connect to Remote
If successful, the DJI GO app will immediately say "Connected" with a WiFi icon followed by the usual firmware check banner up top and the "Enter Device" prompt on the bottom right. |
