Hello,
we are using CC8521 in our board in Host control mode. we have Sam4s to control the CC8521.
recently we figured out that, if we dont connect the CC8521's I2C lines to the MCU/ADC's I2C line, the CC8521 doesnt work.( transmission doesnt work( our wireless communication doesn work)).
as soon as we connect the CC8521's I2C lines to our MCU's I2C line, it works.
since we are not using I2C of CC8521, we are not sure, why this is happening. we expect to have the I2C of CC8521 to be grounded or pull high and communication works.
would you please help us to figure out this issue?
Thanks
Neda
