using a wemos d1 mini to flash this firmware but wifi didn't show up about wireless-esp8266-dap HOT 15 CLOSED

Hi, @xiezhuojin
This is not a full firmware. You need Espressif’s bootloader.

from wireless-esp8266-dap.

Sorry, I forgot about that. Currently you can follow the readme instructions for download via idf.py, or you can find the appropriate bootloader to download along with the app firmware.

I will support an easier download method ASAP.😢

Hi， @xiezhuojin

You can try using the pre-release version of the following page:

https://github.com/windowsair/wireless-esp8266-dap/releases/tag/v0.1.3-alpha

Using esp8266_dap_full.bin, download it with the same command

from wireless-esp8266-dap.

Tried to use the esp8266_dap_full.bin firmware with the same command, but it still didn't work. But thank you anyway, this is the first time I tried esp8266 chip.

It's weird. Are you able to see any output through the serial port with baudrate of 74880?

from wireless-esp8266-dap.

Here is the command and its output to flash to firmware

esptool  -p /dev/ttyUSB0 write_flash -fm dio 0 /home/kevin/storinator_beta/@documents/hardware/esp8266/esp8266_dap_full.bin

Please point out the place I did wrong, thanks.

The baud rate is 74880. We only concerned with the output results during power-on. Maybe you should manually press the reset button on your board.

Can you please try to execute erase_flash before downloading?

user code done may mean that the flash mode or flash size needs to be changed.

from wireless-esp8266-dap.

ok, wemos d1 mini is an ESP-01/07 series chip. You may need to use qio flash mode:

esptool  -p /dev/ttyUSB0 write_flash -fm qio 0x00 path_to_bin

from wireless-esp8266-dap.

esptool said that chip doesn't support erase_flash. After using qio mode, led blinks but the wifi still doesn't show up. Output of serial

Maybe I should buy a daplink...

Ok，it bring you one step closer to success.. I'll upload a firmware later that shows the full debug log.

from wireless-esp8266-dap.

unzip target.zip, then download it

After reading the log, it said Disconnect reason : 201. So I try to look into the code, and found the reason(maybe). I originally though the dap is trying to create an AP and my PC should connect to the AP to get it work. But instead, this dap is trying to act as a WIFI client to connect to AP call 'DAP', then I created a hotspot with my phone, the dap connected to it and seems everything work perfectly! Thanks a lot, such a great job you did for leading me(not even a hardware guy) to make this to the end!

from wireless-esp8266-dap.

Yes. Most laptops have mobile hotspots which is the reason why the DAP acts as an STA to connect to the PC(AP).

I didn't think it would be ambiguous, thanks for pointing that out, I'll update the description accordingly in the next release.🤗
