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 want to connect nRF51822 (on a readbearlab ble nano) to arduino micro which uses 5V logic on a 32U4 IC. I know I can use an external logic level shift, but I need...
In table 32 on page 25 of the NRF51 Reference Manual, there are a bunch of registers with the description "Reserved for Nordic firmware design" or "Reserved or Nordic hardware...
Dear nordic.
I am testing with nRF51822, and have some question about hardware stability check.
nRF51822 have Clock Monitor Unit (Clock fault detector)?
Is WDT same...
I am running a standard schedule loop where I wake-up, service any scheduled tasks, then immediately go back to sleep. However, I am observing the following pattern:

Hi,
Everyone,
I have been working with Nordic NRF51422 with keil since laste 4 months.
Now I want to make Dev kit working on windows machine with eclipse GCC

Hi everyone,
When I run 4 instances (i.e., x2 PWM channels) of PWM with S210 (same example as the ant_background_scanning from SDK 10), after few seconds of constantly...
Hi, I am following the tutorial devzone.nordicsemi.com/.../ . to try to use eclipse to program and debug.
I have installed Eclipse on windows and I can compile without...
Timers are defined by a macro: APP_TIMER_DEF. This unfortunately expands to:
#define APP_TIMER_DEF(timer_id)
static app_timer_t timer_id##_data = { {0} };

Hi, we're working on a project that involves constant streaming of gyroscope and accelerometer data from an NRF51822 based module to a Linux machine.
What we've been working...
I am using the ble_uart_app on the dev kit with the nrf52. SDK version 11.0.0. How do I get the bsp_event_handler to get fired on a button release and button push event and...
Hi, I'm using stlink + openocd to flash and debug and it works fine.
But I want to measure the current consumption with nrf51822 debug interface off
Is there an equivalent...
I have a high-speed signal which I would like to sample with the nrf51's ADC. The signal is periodic (80kHz) and is from a low-impedance source (op amp buffer). I don't need...
I've been searched windows sample application for bluetooth.
I got android sample code but I need MFC sample code now.
If you have the sample code please let me know.
