Hello,

I am using WICED Studio 6.2 with CYBT-343026-01 and currently, I am using deep sleep by using wiced_power_save_start(WICED_WAKE_SOURCE_TIMEOUT,30000); API, and as per documentation after deep sleep on wake it reboots the controller every time. But my problem here is that it gives a spike in current consumption up to 8~9 milliampere on boot. Why so? Also, I have noticed that some GPIO pin goes high for some milliseconds during reboot of the controller. Is this is Cypress's known behavior?

Thanks and regards,

Neeraj

Hi,

This is a known behavior to Cypress and it's common.

Before the controller completes the reboot and initiation, the GPIO pins and current consumption state can be unpredictable. Please keep the connected device waiting until CYBT-343026-01 stabilizes down.

Best regards
