I want to realize time synchronization of two RSL10 within 1 ms error.
In my experiment, two RSL10 toggle GPIO at same interval using timer.(timing of toggle is not same)
At the timing of send notification( GATTC_CmpEvt() ) slave reset its timer and at the timing of receive notification( GATTC_EvtInd() ) master reset its timer.
In my way the error of timing was about 3 ~ 5 ms.
How can I improve it ?
Please give me advice.
