Hello,
It's not an issue but rather I'm humbly asking for your expertise.
I'd be interested to do the same kind of classic watch conversion, but I require BLE support so I was wondering if an NRF51822 or similar, with it's relative passive components, would fit in the same enclose like yours.
My objective, feature wise, is for it to still be a simple clock, but with BLE support for advertising and maybe although optionally, generate OTP codes.
What do you think?
Thank you in advance

NRF51822
Has no LCD controller.
If I was to make a new iteration of this project that supports BLE, I'd probably go with an STM32WB55. They have BLE and an LCD controller.
