I recently bought a DIY Pro Kit (version 3.7) and I have the following problem:
no matter what I do, no Wi-Fi hotspot gets created after flashing the firmware 3.7
Here is what I did so far:
- flashing firmware 3.7 via my browser to the included D1 mini controller
- flashing firmware 3.7 via my browser to a different D1 mini that I already own
- flashing firmware 3.7 via Arduino IDE to both controllers.
I checked for the Wi-Fi hotspot with an Android phone, an iPhone, a Linux PC and a Windows PC!
→ nothing. No Wi-Fi network gets created.
Interestingly enough, when I flashed firmware 4.2 for testing purposes:
I GET A WORKING WI-FI HOTSPOT!
I just can’t figure out what’s wrong with firmware 3.7 and why it works on version 4.2.
I assume that it’s a firmware problem, since firmware 3.7 did not create a hotspot on two different D1 minis.
When comparing firmware 3.7 and 4.2 I don’t see anything that would indicate a different Wi-Fi configuration in the firmware.
Can someone help me with this problem please? I am at my wit’s end.
