I was troubleshooting this all yesterday and the day before and finally found the solution to this.
I currently have a TS10 from Youmecity from AliExpress and my headunit started doing th is on the second use.
I renamed my headunit hostname, bluetooth host name and hotspot hostname to the same name, once done I restarted the headunit and my phone (its important to unpair both phone and headunit if you have done so previously), once done repair it and it should do the new name.
It's important to note that Zlink, Tlink and Tlink5 software are all different, you have to use the type that came with your headunit otherwise it will ask you to activate the software. So in lamance terms, if your headunit came with Tlink5 (mine did), I cant use Tlink or Zlink without buying an activation code.
My headunit had Zlink installer in the flahs memory of the headunit, despite requiring Tlink5, so not sure what they were thinking in that regards.
Once you are using the correct software, paired your phone (both modules) and have your wifi receiver turned on (on the phone, not the headunit), Tlink5 will turn off any wifi on the headunit and enforce a hotspot, this is what is required to simulate wireless streaming over a 5ghz wifi frequency.
Now my headunit auto connects to android auto within 5-10sec everytime I turn on the car.
