Re: AP MODE ISSUE WITH CHROME BROWSER

The issue is your not properly sending the data in a way the browser will understand it properly. send(clientSock, "HELLO WELCOME", strlen("HELLO WELCOME"), 0); The browsers wants to know when it receives data what kind of data it is. I.E. is it text/html, image/x-icon, application/javascript and so...

Re: need help with touch GPIO

See if this works for you int threshold = 50; bool touch1detected = false; bool touch2detected = false; bool touch1state = false; bool touch2state = false; void gotTouch() { touch1detected = true; } void gotTouch1() { touch2detected = true; } void setup() { Serial.begin(115200); delay(1000); // give...

Re: ESP32 WROOM 32 won't enter serial bootloader mode

Each strapping pin is connected to its internal pull-up/pull-down during the chip reset. Consequently, if a strapping pin is unconnected or the connected external circuit is high-impedance, the internal weak pull-up/pull-down will determine the default input level of the strapping pins Remove R16, ...

Re: What would I need to enable flashing to a ESP32-WROOM-32

In that case, how would you make this sequence of events happen on a PCB?
Quickly thinking about it I would do something like this. You might have to play with the cap value to get the timing right on GPIO0

Re: What would I need to enable flashing to a ESP32-WROOM-32

That means pulling both GPIO0 and GPIO2(fixed) low. There is more to it than this, you also need to control the EN pin as well. To put the device into programming mode you need to pull EN & GPIO0 low. Then release EN, and moments later release GPIO0. You don't need to fiddle or control GPIO2 at all...

Re: is there any issue using io0/io4 for i2c?

You never want to use internal pullups for I2C on ANY device. They will all be too weak to do the job properly.
