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, Dear Expert:
I am an Electronic Engineer. We used nRF51422 or nRF51822 at our products, but found the products was easily reset when did +/-1KV contact ESD testing...
now I used sample code of radio
change NRF_RADIO->MODE = (RADIO_MODE_MODE_Nrf_2Mbit << RADIO_MODE_MODE_Pos)；
In transmitter code , I change
while (true...
Story Short: When trying to run the ble_app_uart example on a custom board with a nRF51822QFAAH0 chip, the code faults and resets at the point in tries to call sd_softdevice_enable...
I would appreciate some suggestions on a good development flow to go from an Example to end application
I have nrf52832 on a custom PCB.
I tested several sdk13.0.0 examples...
Using:
nRF51822
GCC 4.8.4
Nordic Sdk 5.2.0
and even Ole Morten's nice pure-gcc setup
newlib-nano and -flto
Within the startup_nrf51.s I found something...
The server has no I/O, so no way to press a button.
Can an attribute cause the BLE to set a bit in Flash, so at the next power up, it will read that bit and know to execute...
Hello,
I followed the instructions of KEIL in www.keil.com/.../ulink2_trace_itm_viewer.htm
However, I cant get any outputs in Keil Debug(Printf) Viewer using printf...
I purchased a bunch of ptr8000 boards off ebay from china to do some testing of the nrf905 without realizing they were setup for 433mhz, and I need 915mhz. Looking at the...
Hi,
I am currently testing a DAC with I2S input supplied by the nRF52832.
But unfortunately no signal is coming out from the DAC, furthermore when reading the error registers...
I'm looking to use the nrf open mesh on battery powered devices based on nrf51822. I would like to enable the mesh for short periods of time to transmit values (~50 nodes...
Hi,
I've just got the example running with one DK as ble peripheral and ESB at the same time uing the timeslot API and one DK as only ESB receiver.
I can communicate fine...
I have used following sources for my application:
profile:
-BleManager,
-BleManagerCallbacks,
-BleProfileService
uart:
-UARTService

Hi,
I've just started to implement the example
github.com/.../nrf51-ble-micro-esb-uart
for the nrf52. And it is now running so I can send and receive stuff via BLE...
