The CYW20719 datasheet shows that there are 2 I2C blocks on the part, and that they both can be set up as Masters.

Under MTB 1.1 / SDK 1.4, it does not seem like there is a way to control the 2 different busses, only 1.

How can one use both I2C busses on the 20719B2 as independent masters?

We will change the document that only one I2C is supported in this device.

I need to check with our FW team to find a way to use both I2Cs.

I have reported a jira to our develop team and also added you in the loop. Need some time to get the answer.

Can we get a status on when the 2nd I2C interface will be supported?  I'm concerned that it was not supported in WICED for many years and wonder why that is the case when the datasheet clearly shows 2 I2C busses available.

Is the 2nd I2C interface not functional?
