Hello,
I am stuck when trying to follow this guide: https://docs.petoi.com/communication-modules/wifi-esp8266 to configure wifi with the included ESP8266 module. Specifically, I am getting the error "A fatal esptool.py error occurred: Failed to connect to ESP8266: Timed out waiting for packet header" when trying to upload the code. It keeps getting stuck during the "connecting..." step. For context, I am using MacOS v12.6.2 (Monterey). I see the serial port connected, and bittle is periodically making a series of chimes via the buzzer which it normally does when connected with the usb module. I've tried with v2.7.4 as listed in the documentation as well as the latest version of 3.1.1 to no avail. I've tried to upload the basic blink sketch as well as the WiFi firmware listed below the test in the documentation. Any idea what could be blocking me here? I've been trying to troubleshoot for about half a day and haven't gotten anywhere. Below is a photo of how things are connected as well as some screenshots from my Arduino IDE. I'd greatly appreciate any help!
I saw you made a three-way connection.
