I replied in the nrf51822 thread. Yes I managed to make it work like the original with BLE stack. And using the wonderful Cypress Proc BLE solution including capsense and lots of goodies . Cypress really rocks! I love them.
The current consumption was lowered to 200uA without being connected and 700uA connected. Those numbers include LEDs current consumption and other blocks like touch sensing.
I'll get back with more updates when it's finished.
Really nice, did you buy the glass plates from there ?
If not, can you please tell where you get them from ? Thank you !
I buy them on Aliexpress:
If you apply hot air it is easy to take off the white "double sided tape" and the plastic.
I have published all the documentation in a Github repository. If someone wants to make PCBs, I recommend that you wait a little longer until you receive my PCBs and try them.

you can add it externally after the fact
... It's not entirely clear, is it adding something to the circuit diagram (hardware)? Or is it a software solution, such as writing a value to a register?
Well, it's been a while, so I' going from memory. There's definitely a hardware component for DC-DC that you can see in the datasheet. IIRC, there's also a software enable as well. Really, though, with these chips, the datasheet is your friend for answering most quesitons. There just isn't much other documentation to go by, aside from thread "nrf52 action!",
Hi, unfortunately I don't have time and patience for doing BOM's on all of my projects but in this case it's not very hard as the external component count is greatly reduced by using the NRF51822 RF SOC which is a PTR5518 module from Aliexpress. Other than that there is the Microchip touch sense controller - MTCH105 and the usual smd resistors(0603) and caps. Other than that you're not forced to use and solder the onboard dc-dc converter so you don't have to worry about those components - you just need to solder the 3V_EN jumper to use the Livolo 3V output coming from the main relays/power supply board.
