Re: New $23 ESP32 audio board on Kickstarter

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

An interesting thing is, when I hold the EN button on the DevKit and run the command above,

Re: Fastest way to transfer data

Can i use http or tcp for file transfer while having the esp32 as an AP?
http uses tcp (mainly).
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.
