Thank you, Bogdan. Your work is a great help in developing the channel hopping part. As there are only 14 weeks in GSoC, the schedule is a little tight. However, I will continue working on this project after GSoC (if I am selected). And Channel hopping will be the first task after I finish all the tasks planned in GSoC.
