Led blue flashing (no bridge established)

seboss1111 commented 4 years ago

Hey guys ! ( i'm a engineering student passioned about drones <3 ) I've an issue for a while now... I'm not able to established a bridge connection with ZeroTier : my sc2 is blinking blue..

BUT the weird thing (probably related to my issue) is that it is WORKING SOMETIMES 👍 (SOLID BLUE : But i'm not able to get a video feedback or any feedbacks from the drone with freeflightpro, and then, after 2minutes, it disconnects and goes back to wifi mod)

Of course : -in ZeroTier, both devices are "ONLINE" with bridge enabled -everything was configured (ssid, pass, APN, etc...) : not surprising if i can get solid blue sometimes -in wifi it's working properly (feed backs)

I really need help here, i won't be able to solve this huge issue alone... I can get you every infos you need.. just tell me what you need and what to do ! ;) Thank you all in advance 💯

Hi seboss, zerotier reduced their network of relay nodes drastically in August. And as the FreeFlight Pro/SC2 connection is very sensitive to latency, you most probably get disconnected before the video stream even starts. What carrier are you using? I assume you are getting a relayed connection. If you can manage to get a direct connection, this issue will not occur.

I've pretty much tested everything now... And unfortunately my carrier is here on your list : "Bouygues telecom" in France.. Yeah I'm quite sure that it is ZeroTier the problem here.. :/

Any idea on using something different? 💛 Even with an old raspberry pi zero, as long as it would work for me, I'm ready... Tell me... 👍

Hum... it works perfectly for me with Bouygues in France. BUT, it seems the apn I use is not the one listed in github... I used the apn given by Bouygues (something like mmsbouygtel.com) and made sure to have good 4G level on the phone. I have 2 B&you sims with this same apn, then glympse reports are telling “direct connection “ and 50ms latency... I posted my maiden flight with 4G on YouTube, then I can swear it works.

Yeah I discovered that too while searching infos on my network provider, under network configs in my phone (apn : mmsbouygtel.com) I have not "B&You" but "Sensation" offer on my phone (with the free multi-sim option the second for the sim in my drone : the two basically share the same internet offer --> maybe that's the problem???) Anyway you give me hope thanks a lot @tuttoto !!! 👍

it could be. if you can borrow another SIM (different plan) for a quick test that would help to find out.

I investigated sensation and b&you contracts (only marketing differences, the technical infrastructure and parameters are identical), and found out that apn for phones are “mmsbouygtel.com” BUT apn for the second sim (when subscribing the “multi-sim” option) is “ebouygtel.com”. I have 2 “phones” SIM cards (allowing voice/sms/mms/data), one in my phone, one in the disco... with “mmsbouygtel.com” for both. You have 1 SIM card identical to mines , but your second one is not allowing voice/sms/mms... only data, and “ebouygtel.com” as apn... It is maybe not the main issue, though, as I made tests with an Orange SIM card (an other phone... sharing the connection with Skycontroller... and it worked well enough on my desk... (I didn’t fly with it)) and managed to have connection and video...
