Anyone got BigTreeTech BTT’s ESP32u ESP32e Wifi Module working with their Octopus or other BTT boards? Am trying to figure out whether the module comes with web server firmware already installed, or, if and how we should install. Not seeing much info on BIQU product page and BTT repo.
Plugged ESP32U module into Octopus, then powered up the board. I see and join wifi network e.g. ESP_DC1234, but http and https requests are refused. Getting Ping responses though.
Pinout picture in BIQU product description is for the smaller ESP32 daughter board mounted to the Wifi module. So that pinout diagram isn’t useful…
BIQU’s ESP32U Product description page doesn’t mention this, but to me, the module dimensions looks like the same layout as AI thinker’s ESP8266 based ESP-07S wifi module… So, I’m guessing the pinout for reset/serial/power/programing pins will be is same… Maybe…
Currently hunting around BTT’s github repo and elsewhere for info on ESP32U and ESP32E. Current plan is to use my ESP01s programmer with bunch of dupont wiring to the ESP32U module based on the ESP-07S pinout, and try to upload ESP3D compiled to ESP32 firmware. Wanted to check in here incase someone’s been down this path already? Cheers!
I flashed mine, and I am pretty sure I posted all the hookups and some info, so I would not lose it. There was very little info and it took me a while to get it. If you can’t find my post I can take a picture when I go out to the shop. I know I left it plugged in as well.
This is what I have. Pretty sure rts and dtr are just for the bootloader or something. Dam, swear I wrote all this down somewhere, it wasn’t easy the first time.
Wow, those are some notes! I wasn’t going to dive in too far until they give me some quotes for the new octo EZ version. I got complaints about sticking on heatsinks and those are pre installed.
Once you get that on there, you should be able to do OTA updates. I wonder if I can get them shipped, preflashed with esp3d. If I send them the bin they might. Won’t know until vacation is over.
