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.

Hi there,
When I tried to send data chunk (it's about 8K) to phone side according to this , the speed is much slower than 1K/s, and what's more, it's disconnected with...
Hi,
I have a problem in CRC of setup message for nRF8001,
and I already try the CCITT-16 algorithm with below conditions:
Poly = 0x1021,
Init = 0xFFFF,
Ignore all...
Hi,
I want do RSA on NRF51822. The build environment is GCC. And the develop base on S120. The RSA need 1K to do calculation. If I enable the RSA calculation, the APP may...
Is there any high-level documentation of the nRF52-DK (PCA10036) connections?
Studying the schematics, I have inferred some of the intents, like:
built-in JLink automatically...
Hello,
I'm starting a new nRF51 project on mbed for a custom board. I wish to know what is the "cleanest" way to define pinout (what file to edit) ?
Thank you
Hey,
I'm working on integrating nrf8001 with STM32, currently trying to write my own stack.
Upon reset, I read the DeviceStartedEvent, 0x81 and it shows "0x02 0x00 0x02...
Hi,
I am new to the nrf51 and I building a complex ANT application. I have part of the ANT application working but I would like to debug with printf() statements to find...
After testing with 5-6 different phones it is evident that there are major differences in how well BLE is actually supported. The Android/Iphone (and manufacturer SW) version...
Hey there,
I am looking at making some standoffs for the NRF52 Preview DK, and was wondering if someone could give me a 1:1 scale version of the DK so I can print it out...
Hi.
I am noobie and i have follow this guide devzone.nordicsemi.com/.../ .

Hi,
I want to generate a sine wave using the nrf pwm library and a timer CC instead of a delay that is used in the sine example here to get better accuracy.
It basically...
Hello,
I am adding an extra characteristic (of 6 bytes) into one of the services that exist in the default beacon app. Then I try to update this characteristic using master...
Hello Guys,
can someone help me solve this problem (see picture below). Apparently Keil is missing an RTE and CMSIS component. I don't know where to get them. I installed...
Hi
I am trying to get to the bottom of a problem I am having with sending a buffer of data on connection and indication enable.
Here's what I do:

Hello Everyone,
I am trying to use a display (through SPI) in a custom board with nRF51822 and SoftDevice S120. All works great as long as I call the SPI methods from main...
