Or to the nrf51822 module directly (SWCLK - SCLK, SWDIO - SDO): You may hook it up to the dev board (SWCLK - SWD, SWDIO - SWIO): Just hook it up, run nRFgo Studio, flash softdevice, run Keil, flash firmware and you're good to go. This is how it looks with Segger (it doesn't power up the chip so the board needs external power):
It's a bit more expensive than stm32 but it's worth it.Īlso (a slightly cheaper solution) is to buy an ST-Link.īought it here just $3.20 from the same seller. Managed to flash and got a working bluetooth 4.0 keyboard (use nrf51sdk9). With Segger I was able to use nrf manual and Keil as here Segger: just $15, reliable seller and fast shipping.
Failed to receive the stm32 for a while so I bought Segger J-LINK and dev board.
