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
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...

Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
I see some interesting phenomena on the power profiler (with nRF52840) that would need some help to explain. I am using the ble_app_uart code from ble_peripheral folder in...

Hello everyone,
We're currently in the process of porting our code from the NRF51 to the NRF52 (both without any softdevices). Everything compiles and seems to be working...
Hi all,
I am making a device which involves using nfr52832(PCA10040) to communicate with a NAND flash through spi to store data acquired from the ADC. After all the data...
After performing the first ADC operation (4 channel scan, sample rate controlled from TIMER1), the power consumption stays at almost 4 mA for the nRF52832.
Why?
Initialization...
Hello, as oppose to S110, the function sd_ble_enable for S140 now includes one more parameter p_app_ram_base, which points to a value that stores the app base ram address...
In this tutorial

There are two additional files added to the template project
ble_cus.c

I understand that...
My peripheral uses a generic sensor service which I use for various sensors. Most of the sensors only have one integer as value and can be abstracted the same, hence I made...
Does the Thingy:52 use the default transmit power of 0dBm? I didn't see anywhere that it could be changed from the app or that sd_ble_gap_tx_power_set was called anywhere...
Using Keil MDK Lite v 5.22, writing code in C for nRF52, with SDK 12.
Example code works.
How does one declare a function, define it, and call it?
I've created a...
