Ratings and reviews

almost bricked my Dev board claimed it uploaded the bootloader, but checking afterwards the memory was all ffffffffff try it again with the same exact bootloader but a different app and it worked perfectly so yeah

this app is awesome! the only thing is that i don't get the serial monitor option, but for flashing and other? it's great!

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!

What’s new

Added spiMode, spiFreq and flashSize options. Those only apply to the first file you flash, and it must be a bootloader (no support on BW16).
Not all values will work with your specific device, be cautious, it wont break anything though;
