I have been working on the 128kB version of the nRF51822 chip, but it seems like the OTA versions of my firmware will not fit with the gcc toolchain. So, I will continue working with the 256kB version.

Yageo has a new chip antenna coming out that is 2.7dB peak and still a small traditional chip antenna. I have had issues with the Molex antenna getting ripped off the board in some situations. So, when possible I will try the new antenna.
