DOUBT ABOUT BLE HEART RATE COLLECTOR EXAMPLE

[Iturcemi_Alejandro]

Hi all,

I am trying to develop the BLE Heart Rate Collector example on the nrF51 Development Kit. As far as I read in the Nordic web (http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk51.v10.0.0%2Fble_sdk_app_rscs_relay.html) I need to download the "ble_app_hrs_c_s130_pca10028.hex" in the "Collector Board", but I don`t know what *.hex I have to download in the "Sensor Board" ...

Thanks in advance!!

Regards, 

Alejandro

Hi,

I recommend nRF5 SDK v12.3.0 for new development on nRF51, as that is the latest nRF51 series compatible SDK.

For SDK 12.3.0 the testing section of the example documentation lists and links to what examples to put on the peripheral boards.

Replying to myself here...

Precompiled hex files are found in the "hex" folder of each example, and they all include SoftDevice. Also in the name is the pca number of the DK they are built for, so you should choose the one corresponding to the DK you use for sensor board.

Hi,

I have already downloaded nRF5 SDK v12.3.0. In the "hex" folder of BLE Heart Rate Collector Example (examples -> ble_central -> ble_app_hrs_c ->hex) there is an hex file call "ble_app_hrs_c_pca10028_s130.hex". I guess that file have to be downloaded in the Collector Board. But I also need one more *.hex file to download in the sensor board. The problem is that I don`t know where I can find this file. Since in the example folder the only *.hex file for pca 10028 is the one I have just tell you...

Regards,

Alejandro

Sorry for not responding earlier.

In case you have not found out already: There are one central example (hex files in examples\ble_central\ble_app_hrs_c\hex) and one peripheral example (hex files in examples\ble_peripheral\ble_app_hrs\hex). The precompiled hex files include the SoftDevice, which is the BLE stack.

You may also build the projects from source. If so, you get a .hex file without the SoftDevice, which means you must program the board both with your compiled hex file and with the correct SoftDevice.
