I am looking for cheapest (up to few hundred USD) and simplest Arduino basic solution to track real-time RFID tags distance (also direction if possible) without additional...
Hi all,
I am new to Nordic semiconductor but I could be interessed by nRF9E5. To check if it could fit my requierement, I would like to know if it possible to configure...
Hi,
I am using ADC without external reference and no analog input in order to measure the battery level with a timer (code at the end).
I am also reading several ports...
Hi,
I'm programming the nRF51822 and save some user data into the FLASH by using pstorage_update . It works fine if I set system off mode, and wake it up. I can read back...
Hi,
I have been using nRF51822 with my Android app using Android's Bluetooth Low-Energy APIs.
In order to get more details, I am currently working on integrating the Android...
I'm looking at interfacing a typical Wheatstone bridge sensor to the nRF51822 ADC. This particular sensor only requires a mA or two for excitation and the output fits within...

Hi there,
I'm using nrf51822 timer1 as the timer for some time-critical task, and I'd like to ask two questions about it:
What's the precision of Timer1 if the...
Hi
I am using nRF51822 (pca10001).I am unable to discover my device. I used the ble_app_template_s130_pca10028 as my base and added the code for gpiote handler as following...
Good day,
I tried the BLE Mesh Example located:
devzone.nordicsemi.com/.../
... and for some reason it is not working for me. I posted a comment where the example is...
Hi.
Faced with a strange situation.
Example. All look good when I read code area:
void ex1 (void)
{
uint32_t *addr_out;
uint32_t i,word;
addr_out=(uint32_t...
We've developed a custom board based on the nRF51822-QFAA and an MPU-6050 IMU. It runs on a li-pol battery and uses S110.
I've encountered a strange problem when power...
Hi,
I am working on measuring the voltage on a lithium battery (norminal 3.7V) with a voltage divider on nRF52832. The voltage divider combines a 510K and 360K resistor...
Dear Nordic Engineer,
I need to work on nRF52, my Macbook Air has OSX Yosemite 10.10.5 - I can run "make" or "nrfjprog" only if I copied libjlinkarm.dylib into the same...
We have a custom board using the ISP130301 BLE module (containing a nRF51822, 16MHz xtal, 32kHz xtal). Our apps work fine (gcc, SDK6, S110v7) except for high system on idle...
i don't see where the command queue index, m_op_queue.rp, is initialized.
when queue_process is called, the following line blows up:
fds_op_t * const p_op = &m_op_queue...
Is there a way to reject requests when the whitelist is empty? I support clearing out the whitelist, but after clearing out the whitelist I would still like to reject connection...
Hi,
I'm using the nRF5_SDK_12.0.0_12f24da and S132 on nRF52832. I do the multilink based on the ble_app_multilink_central example. When it has connected to the peripheral...
Hi,
I want to use spi list feature without ppi. Is that possible?
Because I have to use the same spi module for OLED, SPI flash and accelerometer with FIFO, spi ppi...
Hi There, PCA10004_Schematic_And_PCB.pdf
We are working on Nrf51822 chipset and have observed in our case that once we download the code we are able to discover the device...
What I am trying to achieve is single-file executable for nrfutil tool, for performing DFU.
I downloaded sources and built it using pyinstaller. I can succesfully create...
