I found the Space paras to control the time interval between packets. However, there exists a lower bound of around 295ms, leading to a minimum delay of about 0.3s. Assigning spacing of larger than this will work but a smaller space seems useless. I'm asking whether it would be possible to have lower limits and transmit the next packet even faster? How to possibly achieve that?
