Problem with installation on ESP

[WBuschke]

Thanks for sharing this ESP software! Great!
I am intending to connect the dtuGateway to EVCC.
I am using this chip according to FlashDownloadTool: _ESP32-D0WD-V3 (revision v3.1) // Features: Wi-Fi, BT, Dual Core + LP Core, 240MHz, Vref calibration in eFuse, Coding Scheme None // Crystal is 40MHz // MAC: 441d64f880d0
Manufacturer: 68 // Device: 4016 // Status value: 0x400000 // Detected flash size: 4MB

A. Is this the right chip to be flashed with the recommended WROOM binary?
B. Is it needed to flash the firmware binary including bootloader.bin, partititions.bin and boot0.bin from the docs page?
C: What is the right adress to flash the firmware to? Is it 0x1000 according to the readme?
D: I am not using any display; what can I do if the AP does not appear after flashing?

Thanks for your support!!!!

From my perspective the chip should the right one and is e.g. used in a ESP32-WROOM-32 module...

Yes. for first flashing the bootloader.bin and partions.bin is needed...

=> that was my trigger ;-)

With the last release I've made changes in the partitions, but I didn't updated this in the repo... used that point now, to rework the automation workflows, readme and finally the content of all upcoming releases.

Means from now on the factory flash files are part of every release as a zip.

Please check the last snapshot release -> https://github.com/ohAnd/dtuGateway/releases/tag/snapshot

To the last question: the 'easiest' way, leave the device connected via USB and open a serial monitor with 115200 baud - there you can see a lot of debug infos, especially also what is the current state about the AP with the right IP (if captive portal is not working on your site).

Thank you so much for your answer, Andy. May be this explains why I got a failure message regarding the flashing. I will try the snapshot and I hope it will work. I guess I need to learn how to use the serial Interface! Regards and thanks Wilfried

Dear Andy!! It works. Wonderfull. I can see the data on EVCC integration in Homeassistant now. Thanks a lot for the software snapshot and the explaination!
Kind regards Wilfried
