Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

Hi all
Now I can use Keil to compile/load/execute the example project, for example blink.uvproj.
But how to execute/debug on ble_app_hrs example ?
Keil will hang on a...
I am looking for details on the internal temperature sensor on the nRF51822. I would like to use it to get a general ambient reading of the air around the device. Basically...
I want to get RSSI between PCA10001 and PCA10000. As you known, I have to make these two device connected first. If I write my code based on the example of UART, are these...
Hi,

I'm attempting to load the ant-fs reference design to two different nrf51422 evaluation boards. The application builds successfully but I am having difficulties loading it...
Hi
my application is a 9-axis battery driven motion sensor with a data rate about 144 bit per packet at 1000Hz i have to transmit over air. Low latency (<10ms) is extremely...
Hi,
is there any Example to use the UART ?
I need an monitor while the application is running, is the UART COM Port the right one for this?
Is there an example with...
