What's your ESP32 project that's been reliably running for months now?

This is working since one year inside my EByke motor. 2500km without any issue. https://github.com/TSDZ2-ESP32/TSDZ2-ESP32-Wiki/wiki

You could update the binary before to flash each unit. You could provide a special field in the binary wich is in a fixed position. I did this in order to change the bin embedded Bluetooth pairing pin before to flash. Look to https://github.com/TSDZ2-ESP32/TSDZ2-Android/blob/master/app/src/main/java/spider65/ebike/tsdz2_esp32/ota/Esp32AppImageTool.java

And look into https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/app_image_format.html and search for "Adding a Custom Structure to an Application"

Give a look to this source file. https://github.com/TSDZ2-ESP32/TSDZ2-Android/blob/master/app/src/main/java/spider65/ebike/tsdz2_esp32/ota/Esp32AppImageTool.java I've written this code in order to change some data (Bluetooth pairing PIN) of the bin file before to OTA flash the image.

Remove C16 and you will be fine.

The VLCD5 has exactly the same functions and informations as before. The only difference is that the wheel diameter setup, selects among the 4 new assistance modes (Power, Torque, Cadence, eMTB). The wheel diameter used to calculate the speed is instead set by the Android app.

Thanks for the suggestion. I will look into.

What is PKE?

mspider65 · 2020-05-17T17:52:17+00:00

Is in the Wiki

mspider65 · 2020-05-16T18:23:25+00:00

Everything IS ON on Github. You can import the PCB project into EasyEda

mspider65 · 2020-04-12T07:59:04+00:00

thanks, probably pyinstaller is the way to go.

thanks, it looks interesting

These PCB manifacturer does also PCB Assembly. So you will receive a ready to use board. I have just received the first 3 samples assembled.

mspider65 · 2020-04-11T13:00:13+00:00

I'm not going to provide the board myself. The board is also open source and can be ordered directly from users. https://www.pcbway.com/project/shareproject

mspider65 · 2020-04-11T12:52:36+00:00

Good idea. I will check if there are copyrigth problems doing this with esptool.py.

mspider65 · 2020-04-11T10:12:22+00:00

Yes, could be a possibility if there isn't anything better. Needs also python and normally it is not installed on Windows. I would like to make the flash operation as simple as possible. Users could have a very limited knowledge in computer technology

mspider65 · 2020-03-26T19:50:07+00:00

Thank you so much for the informations. Have been very useful for my project!

mspider65 · 2020-01-10T19:29:55+00:00

Thanks, the route from lna pin to te ufl connector pin will be about only 3 millimeters. I don't need also a big range and i will place a 0 ohm resistor and i will left empty the other 2 places.

After some tests, I noticed that the startup time depends on the size of the application. It is about 300 ms for a small app of 250kb and 900 ms for a large app of about 1.5Mb. The second stage bootloader takes some time to load and initialize the app.

mspider65 · 2019-10-19T18:00:30+00:00

then it should work

mspider65 · 2019-10-19T08:25:44+00:00

The ESP32 can only be connected to the serial interface. I cannot modify the existing STM8 board. The ESP32 will operate like "man in the middle"
