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...

I've managed to get my 85122 dev board set up on parallels on a mac and get 'blinky' uploaded to it using Keil and nrfGO studio. I then changed blinky to do something else...
What is the exact meaning of this error code? Is the pipe busy? The nRF8001? The peer? Is an indication of something I did wrong, or just a indication that something needs...
Hello,
finally I am developing an application for iPhone which works together with the nRF8001/nRF8002 which I was able to buy in a reasonable housing already. Therefor I...
First, I'm just beginning bluetooth solutions, so I apologize if my question is dumb :)
I have 2 Arduino boards, with 2 nRF8001 shields.
I want to connect them. After...
Chip: NRF51822
Per the documentation the band gap voltage is 1.2V however on my board when I apply the voltage 1.5V to AIN2 i read the following value from the ADC: 209...
I am completing a schematic using the nRF51822 part. I will be supplying the part with a 3.3V supply. I will use one of the ADC inputs to sense battery voltage (up to 10v...
Hi all,
What is the maximum data rate for the nRF24AP2 when using the Synchronous serial interface?
I cann't see it in the datasheet.
Is there anyone can answer me...
I was using nRF Master Controller app on Samsung S4 to connect to my Ble device. However, after connected a while, the device will be disconnected automatically while I was...
I'm getting started and have an overwhelming amount of stuff downloaded which I'm trying to make sense of.
Which of the examples in the nrf51 SDK use the Softdevice and...
Hi,
I'm using a NRF8001 shield with an Arduino Leonardo, everything connection wise seems to be working. I'm using the "ble_my_project_template" and uploading various services...
