WICED Studio Wi-Fi Combo

[Anonymous]

Hi,

I'm looking for examples of low-power / system-off (power off) modes using the bcm43362a and haven't been able to find any in WICED SDK 3.3.1. I'm using the MXCHIP EMW3165 (STM32F4 + BCM43362) for testing power consumption. Switching to power-off state in the host MCU after wiced_deinit() doesn't seem to help much.

Thanks

Thanks, I'll try DTIM intervals and get some measurements. I was looking for a complete system-off / power-off with or without ram retention that will allow battery powered applications to further reduce power consumption.

Would wiced_deinit followed by initiating stop mode or deep power down mode on the host mcu work ?

Thanks

The lowest I get to on the MXCHIP EMW3165 module with DTIM3 is around 25mA with active listen. This might be due to other losses including external LDO etc.

Is there a way to power off the BCM43362 and an example to put the host STM32F4CE11 in system off mode through the WICED API ?

Using RTC or an external interrupt to wake the module up would be good enough for battery powered applications I'm looking at.

Thanks

Maybe someone on the apps team can respond.

You can also try the Developer Forums that were setup for this device here as they seem pretty active: EMW3165 Dev Forum - Index page

Note that MXCHIP is officially a partner now.

My understanding is that they will be providing their own software package based on WICED.

Hi,

Any time estimates or pointers to MXCHIP forums regarding their support for WICED ?

Thanks
