We have some partners with lower power alternatives. I suggest you just be careful in selecting the proper amount of memory to meet your needs.
ACKme has some very low power solutions for you.
You can use our hardware either using the WICED approach or via our API called WiConnect.
I was going to respond yesterday but we are on the brink of a new WiConnect firmware release that offers even lower power modes and I wanted to get you those numbers too.
The ACKme designs typically use the BCM 43362 and then a different core and memory depending on the features or target market we aimed them at.
Maybe we should chat offline so I can better understand what you are trying to do and then I can help dial you in to the solution that may best suit your need.
So neither of us end up publishing our email addresses here in the forum, can you either call me at +1 408 402 5708 (California) or shoot me a quick note via our contact form? (ACKme Networks Ticket Tracking)
