The SHARP memory display worked with the mods, time to test the uLow BLE code. Crossing fingers, a lot of interdependencies there.

If it works out of the box, I need to start the full overhaul with ultra-low-power code for final pre-release alpha version.

Wow. It worked. I'm mildly impressed. Time to take a break and tomorrow start re-writing on a fresh head adding the ultra-low power event driven code.

Goal: 10uA unconnected in -40dB advertising mode. On two CR3032/1Ah total battery pack that would be 100000 hours, or 4166 days, 347 months, 28 years.

I ordered a nano-ampere meter to measure ultra-low current, let's see how that goes.

Well, 28 years, I very strongly doubt that's even possible due to self-discharge. If we can get anywhere between 5 to 10 years on a single battery with intermittent BLE including notifications such as email, alarms, etc, that time's a noble goal. 

As Bilbo said, Time! Time!

Below is the current consumption with full BLE and display... <10uA, yeah, baby, yeah!

Cheers!
