Hi, friends, I met a strange problem!!!
In bluetooth sytstem, the tolerance of freq drift of fc for a packet with 1/3/5 time slot is 25KHz/40KHz/40KHz. And the test result verifies that the longer packet with 3/5 time slots would have higer freq drfiter than the one with only 1 time slot (625us). But why? I think, the longer the time spent, the more stable the LO would be and thus the LO frequency should have been more stable with less drift.
Would any one of you please enlight me in this question?
Thank you in advance!!!!
Kind regards!!!
