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.

I am trying to port blinky_blank (no SoftDevice) to my target and started by creating a custom_board.h header file with correct GPIO pins for the LEDs and duplicating blinky_blank_pca10040...
Can anyone help me reading IO capability in Android? Basically there is a known bug in some Android versions across different manufactures where Android reports wrongly IO...
I want to use chacha20 cypher to encrypt and decrypt a 64 byte message and send it over BLE. I tried using wolfSSL, cifra both of which provides the implementations but there...
Hi,
To measure the transmitted RF power (to reach EN 300 328) we Need some ATT commands to set fix channel and maximal output power. In additional we test the EN 55022...
In this previous discussion on minimizing power consumption on the NRF51-Dongle, it says:
You are using evaluation kit or
development kit and LEDs are connected

My system is a BLE peripheral with 2 states. There is a characteristic that represents the state, and it can take 2 values: 0 and 1.
You can read the state, write it (force...
When the supply voltage drops below 0.6V and then get back to 3.3V the nrf51822 starts up in an undefined state and often some flash pages are corrupt after that. Is this...
Hello,
We're currently running softdevice s310 v2.0.1 with SDK 7.1.0 on the nRF51422-QFAAE0 (ie. rev 2). We're planning on upgrading to the nRF51422-QFAAF0 (ie. rev 3)...
Hi!
I was using SDK11 alpha previously and when the official version (89a8) got rolled out I started integration. First thing was the missing S210 and S130 softdevices...
Hi together,
I'm using the NUS example (NRF52832) for client and peripheral, which is running quite well. My goal is to inform the peripheral application when notification...
Hi,
I am using nrf51822 chip and i have compiled the TCP Client example from IOT SDK in eclipse.I am using Master control panel as a central device to discover the device...
I want to measure a current consumption for the 3rd-party evaluation board which has 32MHz crystal and 32KHz crystal, and there is not PO.18 on the 3rd-party evaluation board...
Hi,
I use nRF51822.
Is it possible to change a beacon timing of the advertiser by a trigger of the acceleration sensor in the advertising mode?
Thank you for any...
Hello everyone,
I compiled the nrf51-app-button-examples without any error and warnings but it is showing me this error (No cortex -M Device found in JTAG chain / Target...
According to PCA10028_Schematic_and_PCB.pdf (Rev 1.2.0), page 7, there should be SB22-25 surrounding TP5-8:
On my PCA10028, I have TP5-8, but no SB's there:
