Hi,
Thank you for suggestion,
We will consider it and let you know further updates.
Alternatively , does ESP32-S3 mini supports clock stretching, when it is acting as master ?

Hi Sprite,

We have observed that the previously mentioned I²C bus issue also occurs when the MPPT charger (LT8491) is powered and it is continuously occurring but rather randomly . Could you please confirm whether the ESP32, when operating as the master, supports I²C clock stretching?

Thanks and ...

Hi Sir,
The ESP32S3 always has support for clock stretching enabled.
Is it applicable for ESP32S3 acting as master also.
Then that is your problem. The LT8491 is getting starved for power, and tries to draw current from your I2C lines to stay alive; unsurprisingly, an I2C bus doesn't really like ...

Thanks, Sprite,
For your support,
Is there any way we can enable clock stretching in the master mode.
"Sounds like the LT8491 is only using the solar panel as the power source, and effectively takes down the I2C bus when that doesn't provide enough power (probably because of internal ESD diodes ...

Hi Sir
In my project I am using ESP32-S3-MINI-1U-N8 as the main controller unit, It has 4 slaves in its I2C
1)EEPROM
2) Fuel Gauge
3)MPPT Charger
4) GPIO Expander
The LT8491 is battery charger IC whose input is from solar panel. When I probe the I2C SCL line of the MPPT charger LT8491 we found ...
