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.
...
Hello,
i'm programming an iOS app to connect to the nRF51822 (peripheral). The Problem: Any kind of authentication and encryption is needed, but in the final Product the...
I've seeing random crashes at that originate from ll_lm.s0.c:404. It seems to be happening when I have uart logging turned off. I don't think i've seen assert callback called...
Says it all in the title. I'm making a sensor which puts its data in a non-directed non-connectable advertisment packet. I want to read the sensor just before it is sent....
Hi,
We are designing our 2nd pass design based on nRF51822 this would be our production version PCB.
We would like to have our Schematics,Layout and BoM reviewed from your...
Hi,
I am using softdevice-7 and SDK 6.1 for our application. I want to implement static key pairing for serial port over ble application "ble_app_uart".
I have implemented...
I have a 384 byte, writable, variable length, vloc user characteristic and I want to trigger an event when the write completes so my application can operate on the data. ...
Hello-
I am trying to program a custom nRF51822 board with a J-Link-lite.
From the J-Link-lite, I am using the 10-pin header and have it wired like this:
I'm using pins...
I have a situation where I need a software PWM for several channels, which are multiplexed via a shift register.
The output loop needs to run at several kHz for this to...
Because of the limitation in the GPIOTE hardware that only one channel can be connected per GPIO , care must be taken when changing a PWM duty cycle. If for instance the compare...

As you see,GAP Disconnection，I don't Know how it works...
Hi Nordic
I do not know why sometimes program can build pass in keil ,but can make nrf51822 do not work and unable download program . For this , I have damaged a lot of...
Does the nrf51822 support 2 spi masters (on different pins)? I want 1 spi channel to talk to one set of peripherals, and the other to talk to another set. I see SPI_MASTER1_ENABLE...
Maybe question similar to this one devzone.nordicsemi.com/.../
Can I use the interrupt generated by RADIO_IRQHandler(void) while implementing another protocol?
At the...
