CC2650MODA: BLE 4.2 Security on Dual MCU Solution (MSP432+CC2650MODA)

ScottChiang

Part Number: CC2650MODA

Dear Sir:

I am using dual MCU (MSP432+CC2650MODA) and project zero (TIRTOS) as an example for my project. I found out that I can not go into the Low power mode LPM3 if the BLE task is includde in my project. go to LPM3.5 is ok but not go into LPM3. LPM3.5 shut down SRAM (except bank0). Is there a way to solve this problem?

Hi Scott,

This has to do with the UART driver power constrains, if the UART is open, you will not be able enter to LPM3 therefore you will need to close the UART driver (run SAP_close) to enter LPM3.

Just remember that after waking up, you will need re-initialize SAP.

Hopefully this helps.

thanks. It can go into LPW3 now.
