Irfan, the first message came through, there is no need to repeat it. When writing messages like these, it helps to specify what you’ve tried to figure out the solution. Short answer: These blocks append a bit sequence at the tx side, and find the rx sequence on the rx side to find the first bit of a packet. MB
