Hi Sandeep, I would suggest you to use the values 0 and 127 for your thresholds to determine if it works. The reason is if you go by 2's complement representation, then 255 is -1 which means you are setting to adjacent values. So you might not see any difference.
Please try this and let me know. I'm working on a similar project where I need to disable carrier sense, it would be of great use to me as well. Also please tell me if you know how to build a packet and transmit a packet within the driver, that is not processing a packet from a higher layer but your own packet. Thanks.
