I see perfect adapter from Adafruit Bluefruit LE Friend but need wait a time to delivery and already exists some PT9048 . Why not use and check Bluefruit LE Friend features ? Connect PT9048 to J-Link adapter and start nRFgo Studio Program S110 nRF51822 7.1.0 softdevice Program application blefriend_s110_xxaa_0_3_1_141112_blefriend_debug.hex Connect with wires to USB-UART adapter (only 3.3V !!! Command and Data mode works fine....
