nRF51822 bluetooth chip communication to nRF51 Dongle

[ereichwe]

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?

Try using Master Control panel with dongle and read the incoming data in characteristics window, you will get exact data stream in. Basically it works against service, not against COM Port.

Hi, Right now i do not have device but i have done this from the same window actually by ->select device->and on second window when u connect there will be Rx and Tx showing and corresponding fields named "value", so i u want to send u can select that characteristics from th tree control component and type ur data on the Value field at middle of the window so shown on second window. and if u see what u have received , that u can log to any file or see then and there so updated in the tree control component against field item. this way you can first log the incoming data then see or see immediate real time changes there itself... hope this will help you out.

@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.

@Annim: I did that and I can see only one number (occasionally I see the whole line). What I see is: 32, when I really want to see $PRY 32, -90 , 175 (or something along those lines, not just the 32). And the log file shows only hex and I cannot understand it. I think your way works but my target device is configured/programmed.
