UART bootloader

[Yano]

Hi, Is there a UART bootloader built in to the factory firmaware similar to others like NXP LPC series where a specific pin is held low at reset. If so what pins are used? Thanks

@Yano: I assume that you were talking about the nRF51 series. If it was, the answer is no. There is no factory firmware /bootloader for the nRF51.
