Using nRF51422 for sending bluetooth packets

Troels

Hi, I started using the nRF51422 kit today. Downloaded nRFgo Studio, Master Control Panel, nRF Connect, BLE Sniffer, Wireshark 1.10 (after figuring out that you don't support higher versions), Keil µVision, S110, S120, S130 stacks, and nRF5-SDK files.

I ultimately need to make a program that can transmit acquired data over bluetooth from the chip, but of course I want to test the templates first to understand the functionality.

To test the kit I installed the SDK zip files package in µVision, and ran the peripheral_blinky example. So far so good, the LEDs changed at the 20 Hz frequency I set them to. Now I wanted to test the chip's bluetooth connectivity, so I followed the guides laid out in the ble_peripheral_app_beacon example. I configured it to build the flash softdevice and not the default application. When I turned it on, no LEDs were flashing. I opened Master Control Panel and connected through the COM port, but it didn't find any signals. I then tried with nRF connect and Wireshark with the same null results.

It seems most likely that I'm completely misunderstanding the application of this chip and/or the SDK templates, but I just can't figure out how to get this chip to send anything over bluetooth to my computer. Help?!

    Hi,

    The softdevice target in Keil only flashes the softdevice, you will have to flash the application in addition afterwards.

    I would recommend you to go through the tutorials here on DevZone, especically the getting started tutorial and the BLE tutorials, to learn more about the use of our chips and how to setup BLE communication.

    Best regards,

    Jørgen

    If you want to follow the tutorials, you need a BLE enabled phone or a nRF51-DK/nRF51 Dongle to use with Master Control Panel (MCP). Recently, MCP have been replaced by nRF Connect for desktop. This also support nRF52-DK for interfacing with BLE devices. If your PC have a BLE enabled Bluetooth interface, you can connect to devices using this, but you will have to create your own application or driver. If you have your kit (I'm assuming you are using the nRF51-DK?) connected to your computer, you can communicate with the device throug UART (using Termite or TeraTerm), if this is setup in the application in the board. This will not have any connections to the BLE part.
