Bought 4 DT-06 modules, all of them constantly reboot #32

Hi. I have a problem with my DT-06 units purchased through Amazon in Germany (I ordered some additional from the DOIT shop on Ali Express as well, they will arrive in a few weeks).

My problem is that none of the modules work. After having problems connecting to them using Android devices I set my PC up to auto-connect to the wifi and observed closely the network settings using command prompt. The modules all start. And if I quickly enter the 192.168.4.1 address into a browser I can use the web server interface for around 10 seconds. But thereafter all of the units reboot. And so the story goes on forever.

I started up by connecting them to a 5.2 V USB power only connector. Thereafter tried a TTL adapter providing 5.08 V. And finally also tried to plug in the tx/rx cables. The behaviour is constant: They start, run for around 10 seconds and then reboot.

Now typically, when all goes constantly wrong I usually assume I did something wrong. But in this case the units only need to get the vcc and gnd connected with around 5V DC. So I cannot see what I should have done differently...

I was able to quickly get to the "about" section and notice that the installed SW Version is 3.2.1. image

Any advice on how I can proceed to get my units up and running?

I have the same problem in all the units that have just arrived.

Impossible to have stable communication via Wi-Fi as it constantly disconnects.

Does anyone know what it could be? Are we on the latest firmware version? Or is there a later one that corrects this error?

Thanks
