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.

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.
...
Hi all again guys! I am experiencing a problem with my application: i have a beacon that is sending ADC converted values to a nrf51 DK (via notification), which is connected...
Hello,
I want to use SPI between one nRF51-DK (using SD130 v 2 and SDK11) and another board. I am supplying the nRF with 2.3 V and initializing the BLE and the SPI. I can...
I have a BLE application in mind in which it would be useful for the BLE server to obtain the battery level of the BLE client (in this case, a phone, laptop, or tablet). I...
Hi,
Is Nordic looking to support mbed OS on the nrf51/nrf52 series chips?
Currently it looks like the best supported platform is the mbed Classic SDK, but it looks like...
Hi,
I am trying to make a program for the NRF51 development kit on mbed. I have been able to take ADC samples at 1000Hz which is what I want, but I can't seem to print...
In SDK 11 description od DTM "vendor specific" settings, there is a lot of inconsistency in parameters names/numbers - could anyone help me understand this part?
As for...
Hi,
Everyone,
I have firmware working with our custom pcbs.
It works fine with new 3.3v battery.
But somehow it does not advertise anything with used battery having...
I have a digital microphone chip, it has the CLK, DATA, LR_SEL three pins, now I will pick up the three pin nrf5283 three pin is as follows: CLK connectionI2S_CONFIG_SCK_PIN...
I guess we need some help with definitions. Basically, we'd like to read data from an I2C line. Should be as simple as "set to input" and "read the pin". However...

Using nRF5 SDK v11.0.0, I am working on bringing up new hardware based on the nRF52. I started with code that works on the PCA10040 development board in which we connected...
I need to calculate radio on time in IoT SDK but IoT softdevice don't provide ble_radio_notification (in sdk components) and nvic functions (don't have nrf_nvic.h in softdavice...
