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...
When use the "nRFBeacons" app to update the info on my beacon the following happens:
Go to update tab.
Select "Connect"
Press "SW2" on beacon and see the LED begin flashing...
I am using s110 and nrf51822. I've set up up a long characteristic of 154 bytes.
Sending between 1 and 154 bytes works as expected.
Sending 155 - 160 bytes gets rejected...
Hi,
I tested the nrf beacon application, it allows only the beacons with company identifier 0x0059 (nordic's id). But i need to modify it to support all the device, how...
I am doing rapid development for a project, using the nRF52840 DK. Two key features are USB and BLE central role.
I started with the usb_cdc_acm project and am merging in...
Hi all,
I added newliib-nano to my GCC project, when I use new ( std:: nothrow) I got
I add some C++ flags and link flags:

Hello everyone!
I have been working on getting data from ADS1299 ( ExG bio-signal sensing). I successfully got data from this IC using STM32F407VG (Cortex M4) and transmitted...
Hi I'm using custom nrf52832 board, SDK14.02 and SES. I want use pwm driver to generate 2 channel pwm wave with custom nrf52832. Everything is working fine in nrf52DK board...
Hi,
I am to update the SD version that I am using, and in the documentation to create a firmware packet with nrfutil states that the table can vbe found with nrfutil pkg...

Hello,
Is there is way to read the nRF52 flash memory (any location if possible) over UART without uploading a program in the flash memory for that...
Hello ,
I'm trying create a beacon Scanner.
I'm using the s130 protocol stack on the nRF51 DK , namely the nRF51422 SoC and PCA10028.
what I'm trying to achieve is...
I am trying to work through the MQTT-SN Examples that comes with the Thread SDK. When I use the prebuilt image for the Raspberry PI 3 board everything works great however...
Hello,
I use an I2C device to wake up a nrf52 microcontroler.
If I just use the init function
static ret_code_t twi_master_init(void)
{
ret_code_t ret;

Hi,
I'm using Segger Embedded Studio (with gcc naturally). The standard C++ exception handling doesn't work: exceptions are not caught by exception handler. Is there a way...
I have read a lot of the Dev Zone questions here about the RF Antenna design and read the PCB design guideline tutorials and skimmed some of the white papers. Of course the...
The current example TWI_handler will hang forever is it exits with anything other than NRF_DRV_TWI_EVT_DONE. This can occur if a TWI slave fails to acknowledge the address...
Hi,
Based on the electrical specification of nRF52840's HFCLk, the current consumption seems quite different depends which crystal is being used (attached the screenshot...
Hi,
I have shifted from Arduino to nrf. Arduino is straight forward and with very less dev time. I understand this is way more powerful and next level platform, but does...
I am trying some scanning with a parameter setting, code below. The scan start, I am guessing by the call to nrf_ble_scan_start, generates the error sd_ble_gap_scan_start...
