Just solved keeping I2C open and sending a buffer of data!

Hi, i'm using I2C in master mode(ESP32) to communicate with a single slave(LCD). The SDK is the last one at this date. I'm having some troubles with performance since commands are delayed each other by over 100us. You can see the follow screenshots http://www.image-share.com/ipng-3693-170.html http:...

Thanks, i will for OTA way, downloading from uart

Hello,
I would like put esp32 in boot mode with a serial command, without the use of en and gpiO0.
In a single core microcontrollor, what i do is to jump to bootloader address.
Is it possible in esp32? Should task and dual core system be handled in special way?
