Hi everyone.
I'm getting headaches connecting my ESP to my Teensy 3.2.
I'm confident my ESP is working as I managed to upload a sketch via usb and arduino IDE. The IotWebConf sketch works ok as I have my AP online.
But I can't upload a sketch via my Teensy, nor can I acces the ESP via serial monitor (AT command returns nothing)
I followed this instructables: https://www.instructables.com/id/ESP-12E-ESP8266-With-Arduino-Uno-Getting-Connected/
My esp board is this one: https://www.amazon.fr/gp/product/B07K24YQZQ/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
Here's my wiring:
Esp VCC --> USB 5v
Esp GND --> usb GND
Esp RX with a voltage divider --> 220k --> Teensy RX1
--> 100k --> GND
Esp TX --> Teensy TX1
Esp Gpio15 --> 10k --> GND
Esp EN --> 10k --> Teensy 3v
Esp RST --> 10k --> Teensy 3v
I've tried to reverse RX and TX on the teensy with no success.
An interesting fact is that I have the exact same problem with an other Esp (esp01).
Might there be a problem with my teensy serial pins ?
