Question

What is the maximum value of HS_STARTUP_TIME for BlueNRG-1?

Hi friend,

I want to extend the HS_STARTUP_TIME for BlueNRG-1. What is the maximum value of HS_STARTUP_TIME for BlueNRG-1? I saw the datasheet AN4494 it says that "XTAL_startup = XTAL_startup_measured*1.2*1.1*1.3 = 1.716*XTAL_startup_measured".  So 1953uS--> HS_STARTUP_TIME = 1074. But I use BlueNRG-1 IFR tool calculate 1953uS--> HS_STARTUP_TIME = 800 (0x320). Which is correct? Can anyone guide me? Thank you in advance.

Best wishes

Ted Wu

Hi Friend,

Who can tell me what is maximum value of HS_STARTUP_TIME for BlueNRG-1? What is the size of IFR of HS_STARTUP_TIME? How much will HS_STARTUP_TIME become if it is set to exceed 1953uS?

Thank you in advance.
