Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.
At...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...
Hello there guys i been reading your 100 pg PDF for awhile now and im yet to understand or realize how is it that i add/place/create a payload or data to send/Tx via Master...
I am interested in writing a BLE central that reads data from multiple BLE Nordic sensors. The BLE central will be running on Embedded Linux which uses the BlueZ stack.

Hello,
I've checked the timing diagrams for the CE and IRQ on the datasheet but I would like to know if anyone has actually tested them with an oscilloscope? If yes could...
I am using SDK 11.0.0 on a nrf52832, with FreeRTOS and SD132 2.0.0. I configure the FreeRTOS port so that it uses RTC1 as SysTick. Depending on some compilation macros, my...
Assuming that all peripherals that require the high frequency clock are disabled / turned off / stopped, how long does the HFINT oscillator run after calling __WFI()?
And...
What's the delay from setting the Start / Stop task in an RTC module to when the RTC actually starts or stops? Is it less than 1 clock cycle on the CPU (15ns)? More than one...
Hi, I am using the nrf52 dk to sample two analog inputs through PPI.
My question is if I can use different bit resolutions for each analog input?

Hello !
I have a problem with my program (on a nRF52 board) : when I send a value to the board via BLE, it seems that my static variables are reset.
I noticed that, because...
I need to store data in some moments and if something happen i have to read those data, i have to do a log events.
I use nrf51-dk and soft device s130. This data is taken...

Hi,
I'm new and I'm a student.
I have to connect the adxl345z to my board mb39c811-evbsk-02.
It has an nrf51822 integrated.
Someone can explain which pin of i2c/Gpio i...
We wanted to update the firmware over the air, We needed help for zip file creation(.dat file, .bin file and .json file). There are many links online, We needed an link which...
Hi,
I'm developing to NRF81522 mcu, using a softdevice S130.
The MCU is connected to another device through the UART peripheral.
I'm encountering the next problems...
Hi,
I am getting data from sensor and want to replace some new data with the older one in flash using fds. Right now,firstly i will write into flash by using one different...
I am using the nRF toolbox to upload bootloader and firmware to a hardware project. Our project requires the number of packets (found within settings > nRF toolbox > Number...
