How can I ensure not be Interrupted by radio when I use gpio simulate IIC?

My sensor is off-standard,so I have to use gpio to read and write my sensor. Gpio IIC will take about 0.5ms to get data.

My app need send data every 7.5ms,it seems that IIC data will be Interrupted every 1 second. I try some way to solve this problem and need you advise.

How can I make sure not be interrupted when I get data by gpio I2C?
