driver/i2c adapted to AM2320 . Adding delay when sending frame.

[belph86]

In order to start communication with AM2320 sensor , it needs to be woken up.
Using ESP32s2 as i2c master.
Is it possible by i2c driver create delay in certain step of i2c communication ?
So far I found only nice functions for creating packet but not how to change communication in detail.

Before inventing wheel, was it solved before or not ? Is there any function which may be used in order to add delay into frame?

Attached more details about wake up procedure with sensor.

Hello. I know this is an old post... but I was figuring out if you managed to read the AM2320 using ESPIDF
Thanks!
