We changed the thresold to 70. The trigger rate kept its value around 2. But the rate distribution was not steady. The range of distribution is from 1  to 8, sometimes over 10.

We transmitted some files to ESC to update SFC.

TRD didn`t send any data for 20 minutes

SO

ESC was sending the files, and the remaining ones were just 3.

We set thresold to 72 again because the rate is to high and the buffer reached at 15%. After that, we could see the rate was positioned nearby 2~4.

SO

We just comfirmed all up-loading files.
