#49373 Okay, finally all the parts arrived and i started to solder the components together. So far everything is on the board (so all capacitors / resistors and the HT7333). I soldered the VCC/GND/RST-Pin of the ESP8266 module. The voltage at the VCC pin is 3.3V (so it should be fine). Now i am wondering if the LED on the module should light if the module has 3.3V on VCC?

Edit: Okay, i just soldered Pin GPIO15 and the blue LED lit up once for a short time and then went off. But it doesn't light up again :(

Edit_2: Okay, now i have the phenomenon that the blue LED flashes 3 - 4 times when i connect my battery (with 3.6V) to my PCB but then it doesn't light up anymore. If i reconnect my batterie it flashes again. I also don't see a new Access Point on my mobile phone or PC.
