I2C trough the DS90UB925 / DS90UB926.

Thomas Feller

Hi,

I use the DS90UB925 / DS90UB926.

The communication with the I2C slaves works fine, as long as I choose the BCC watchdog just for 2ms. If this I set this time higher, then the bus is busy and the communication does fail.

Can somebody explain that?

Thanks and best regards

Is it possible that one of your slave devices is not releasing the bus? How is your system configured: are the slave devices on the DS90UB926 side of the link?
