Serial Monitor for both text and plot.
How to operate:
Select your device from the list, you can disable Bootloader auto mod if not supported by your device
Browse and select your firmware / bootloader / partition scheme files from your smartphone memory,
Set the offset for each binary file you want to flash (you may see them in the output of esptool compilation...)
Put your device into Bootloader mode (use BOOT-RST buttons)
Hit the flash/erase button to flash them to your attached ESP32/ESP8266/ESP32S2/ESP32S3/ESP32C3/ESP32C5/ESP32C6/BW16 via USB.
Before the flash/erase begins, you can cancel operation (may need to wait before the procedure completely cancel)

totally works with my samsung galaxy phone a16 I think. as of this writing it works for erasing and flashing esp-wroom-32 for those of you familiar with hiletgo, its the esp-32D. I am going to keeping an eye on this one. Now I can microcontroller on the go. Now if I can get things going through termux like it used to, I will be 100% untouchable, but this app gets me all the way up to 97% so all the same, Thanks dev!

That's a great app but is it possible to add auto upload option to bw16 board Update: Thanks for your quick response I mean upload without press burn and rst buttons to enter upload mode, it's like Arduino ide do for bw16 type c board

Hi thanks, sorry what do you mean exactly ? Bw16 flasher uses automatic bootloader and upload files you provide at the offset you want (in general from 0x08000000 ...)
Update: it is already the case, be sure "bootloader auto" switch is ON, unplug/plug again if needed and just hit flash button...
Please send me a mail if you face any issue

Please add Realtek BW16 programming support . Is it never possible to program this with an Android app?

Hi and thank you. The BW16 uses a different flashing protocol and so this app cannot support it. Sorry.
Edit: not impossible, just very specific. Lot of work required for just one board.
Edit New update take the BW16 in charge finally! Coming soon
