nRF51822 bluetooth chip communication to nRF51 Dongle

I have a nRF51822 chip sending me BLE UART data to my phone and it works fine with the app. No I want to send it to my PC and Read the data (and send commands) via PuTTY.

I think I have an issue with baud rate because I can connect, see jumbled data (like chinese symbols, squares, crosses, etc.), I know that it is coming from the correct device when I disconnect the jumbled data stops.

EDIT: I tried using the master control panel and I see my device and its signal varies around -60dBm... which means it is seeing it. Then I press -> start discovery. This opens up a new window with a read/write command and text/hex box. I press connect, then bond then try reading and it only returns the uuid value and handle.

These are the two windows I see below, should I be able to read in continuous serial data in the second window?

master control panel

characteristic window?

  • @ereichwe: have you made sure you selected the correct baudrate and configuration in Putty ? You can test it by trying to send some string using simple uart library. The configuration should be 38400 baudrate, 1 stop bit, None parity, Hardware flow control On/Off depends on your configuration in the code.

    If you want to try using Master Control panel, you would need to click Service Discovery button after you click connect.
