Wakeup pin on CYBLE-022001-00

[SuCh_2227511]

My BLE project is to use low power mode actively to save energy. The system has no power switch running with coin cell battery is always in Stop mode unless user press the wake up button. However I cannot find the information about the wake up pin in the manual. So I am wondering I need to use hibernate instead stop. Please advise. Thanks.

Hi,

The module CYBLE-022001-00 is built using the PSoC 4 BLE silicon. So we recommend you to look at PSoC 4100 BLE/4200BLE datasheet and PSoC 4100BLE/4200BLE architecture TRM for more details about the wakeup pin.

In datasheet pin configuration tab you can observe that P2[2] is the wakeup pin for this family.

Unfortunately, CYBLE-022001-00 doesn't have P2[2] pin. With that said, the chip can sleep with stop mode but no way to wake up?

Hello,

CYBLE-022001-00 doesn't have the Dedicated P2[2] pin to wakeup from stop mode. You have to use the XRES pin to wakeup from the stop mode.
