Question
BlueNRG initialisation current too high / too long
We've measured the start-up current on BlueNRG1 at around 4mA for 60mS. We've been exploring the cold_start_config and we think the biggest part of the delay is HS oscillator settling time. I believe a few hundred uS is typical for XTAL startup For a low power device this is a huge current_x_time product, at least compared to the average current once settled into a low duty cycle operational mode. If we disable cold_start_config completely the time is reduced to 2.3mS. Can anyone advise on if/ how to reduce this initialisation current / time please? Many thanks!
