nRF51822 reading Heart Rate Monitors

[mikeardy]

Hi, I need to read more than 3 or 4 Bluetooth Heart Rate Sensors (like chest strap, arm band, and so on)... I need to do this using Arduino and some library. Could someone help me? Thanks.

Hi,

If it's not obligated that you need to use Arduino, you can use the nRF51822 as the main MCU and use our SDK examples directly. We have an HRM central example at \examples\ble_central\ble_app_hrs_c.

If you need to use Arduino, could you tell what is your setup ? How you gonna connect the Arduino board with the nRF51 ?

Redbear Lab provides here a library for Arduino to use on an nRF51.

OK I write my own need so you can help me in my project. I need to read multiple Bluetooth Smart Heart Rate Monitors. I need to send to a PC via UART/USB or via rradio-bridged connection the beats per minutes and the R-R interval in milliseconds. So I choose Arduino because in my equivalent project I used ANT+ technology to build a device that can read Heart Rate Monitors and Podometers Sensors. For ANT+ side I use a d52qd2m4ia with a nRF52832 chip. I connected the nRF52 via USB to Arduino and on Arduino ran a piece of software developed by me to instruct the chip to read all data from HRM and podometers so it decode the data in according to ANT+ protocol and send only needed data with my own protocol to a PC software. So, I need now to do the same thing with BLE. I can use only nRF51822 to do this? I need help step by step to write a software to send a PC only needed data. Thanks.
