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.
I'm using SDK12.2.0, S130 ver2.0.1, nRF51822AC.
As I know SDK12.2.0 can conenct 8 peripherals at the same time when it is Central mode.
I want to use it as central...
I've got a custom NRF52 board that uses less than 4uA when sleeping without SPI but after the SPI is initialized (and then uninitialized) the current consumption rises to...
Hi Nordic,
For my application, I want to have the absolute acceleration (without gravity) from a MPU6050. I know that this device can do that because it has 6 axis and...
Hi,
I am trying to maintain a single bit of information through a power-on reset event (sd_nvic_SystemReset();). I am trying to do this through the configuration of an...
Hello,
I'm having problems running the DFU over serial bootloader example. The nrfutil command to update the application fails with message "timed out waiting for acknowledgement...
Hi together,
I'm trying to scan for BLE Beacons and I got the problem that if I set setReportDelay() to a value unlike zero, the onBatchScanResults() method is called and...
Hi,
I am trying to measure the current consumption on my application, and measured some quite high values even after calling sd_app_evt_wait().
After reading through some...
We have a product that uses nrf51422_CE_AA, Revision 3, 256KB ROM, 16KB RAM, PCA10028, SDK 8.0.0, S110. We have sold over 8000 devices of our first product. Currently we are...
Hello,
My problem is to much current c.a. 40uA in POWER OFF mode. Below attach code:

I am getting no radio (as in not being able to pick up advertisements packets) from my custom nrf52832 board. The antenna design is a hack so I am not looking fo stellar performance...
We are looking in to developing a generic class to connect and handle our BLE devices for use on mobile devices such as Android and iOS.
Now since we want to have as less...
Hello Experts,
I am running the following examples to test the DFU bootloader in gcc and eclipse environment.

I found a problem of the nRF51822 in boot state.
Power on reset is not executed occasionally when used dying battery.
The problem occurs in the following steps:

Hi All,
I'm having a BTLE_CONNECTION_TIMEOUT when I connect the device in Master Control Panel 3.10.0.14 while the chip is not in debug mode.
The device connects without...
