After power-on, the pairing indicator does not flicker quickly, with a probability of 20%. However, after a long press of the reset button, the indicator flickers quickly, and the pairing is successful. Why?

If the pairing indicator does not flicker quickly after power-on but flickers quickly after a long press of the reset button, the module has been paired during power-on instead of in to-be-paired state. Therefore, the indicator does not flicker quickly after power-on.
