Re: New $23 ESP32 audio board on Kickstarter
I wish you the best on your Kickstarter project. If I may suggest something about Kickstarter the video. IMHO, the video would have been much better if you had shown it in action.

Re: I can't flash ESP32-WROOM module in my project
Actually you dont need to do it, its enough to pull down IO0 and then connect to power supply. Sure, you can do it that way as well. But why bother when the EN and IO0 signals are built into the programming adapter. Just run the extra signal line. If your going to have a way to pull IO0 low, you mi...

Re: Error: JTAG scan chain interrogation failed: all ones
Not really. Holding the EN down hold it into a reset state.An interesting thing is, when I hold the EN button on the DevKit and run the command above,
how about providing your JTAG pinot to the module.

Re: Flashing Bare Esp32 WROOM
The correct way is push "Boot" and "EN" buttons at same time then release "EN" button, then wait about 0.25 sec and release "Boot" button.Then I push the "Boot" button and "EN" button same time and release the EN button.

Re: Fastest way to transfer data
http uses tcp (mainly).Can i use http or tcp for file transfer while having the esp32 as an AP?
tcp is to ensure your data get there correctly with no dropped packets. udp is a send and forget method. udp is faster, but you are not assured that all the data will get to the client.
