ESP32-C3 WiFi signal issue
In one of my projects, I decided to use a board that was new to me - the ESP32-C3. Previously, I had used the standard dual-core ESP32s, but I needed something compact, and the C3 Supermini was a perfect fit. I took a new module and immediately soldered it onto a breadboard. Then I started porting my code—some issues came up, but fixing them didn’t take much time. And only after all this, I noticed a significant issue: the Wi-Fi access point (AP) wouldn’t start. The code executed without any errors, but no device could see the network from the ESP Supermini. “Okay,” I thought, “maybe the module is damaged.” I took a new one out of the package - and it worked as expected. Well, I figured I must have killed the first module with static electricity or overheated it while soldering. I desoldered it from the breadboard and, just in case, powered it on one more time. And surprisingly, it also worked! Just like the new one. I investigated various factors that could...
