BLE Wont go into DEEP_SLEEP when WDT enabled with Interrupts
I've implemented the BLE low power mode using CyBle_EnterLPM(CYBLE_BLESS_DEEPSLEEP) as suggested in AN92584_001-92584_0A_V. Works great and I get about 1.2uA current consumption. No other components just the BLE.
When I add in a WDT in free run, still works... 1.2uA
As soon as I implement a WDT interrupt, even with a 2 second period, doing noting but returning, my consumption runs around 6-7mA
I can provide code but it's pretty must straight out of the app note. I've tried using the "internal isr handler" and my own custom handler. Just curious if someone else has run into a similar issue.
