Hi, I'm using the nRF8001 in an application that requires security so bonds to the remote client/central. My device supports firmware upgrades that may involve new nRF8001...
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...
Hi,
I'm working on a project which uses two nRF51822 (SD130 and SDK v11.0) on mobile devices. Device A is continously advertising and device B scans for a fixed interval...
I'm looking to sync an ADC reading with the PWM output. I'm using PPI for this but fails to make it synchronise properly with the PWM.
I'm getting interrupts and sampled...
Hello,i am using nrfsdk with softdevice 6.0.0 in my application and by using it i am trying to connect my mobile uart application with my BLE .but i am facing some issues...
Hallo all
I have an appliation using the LOG for TX output to uart,
I want to maintain this code but to add RX based on the app_fifo_init,
how can they coexist ?
thanks...
Hi,
I would like to use the nrf52 as my bluetooth end device, which inturn has to communicate with the Bluetooth IOT gateway like Rigado module or Nordic gateway APP(which...
Hi
I am using SDK 14.0.0 and soft device S130.
I am planning to add SPI functionality to BLE's sample code.
However, when moving to the next instruction after SPI data...
I am developing a beacon using nrf52810. This beacon will advertise iBeacon as well as Eddystone packets. And user should be able to configure some of the beacon paramters...
Hi Nordic,
I am using the example nrf_app_interactive with nrf52 DK. I am using it as a central while connecting to a peripheral. This peripheral has a lot custom services...
Hi,
I need implement a single Byte transaction on SPIM.
I implemented a stop as documented in

It works only for the first...
I want to use the RTC Tick Event as my system tick. But on both the RTC0 and RTC1 my programm freezes after about 8min.
It looks like the Tick interrupt is still served...
Hi,
We are currently at the process of manufacturing prototype boards, the manufacture cannot do pitch size under 0.25mm. They kept telling us that the chip's BGAs exceed...
Hi, I got a nrf51822 board and a st link v2 mini as shown below. I have been trying to connect the nrf51822 board so that i can upload code to the board by following this...
Hello folks,
I'm newbie on NRF, I have NRF51422 with Keil IDE and I want to create a mesh network on that kit which will continuously broadcast the data of sensors to the...
I am beginner to nrf51 i would like to increase my expertise on nrf51. Are there any recommended books/ tutorials/ weblinks whcih could help me to gain a better understanding...
Hi there,
We have designed our circuit board with the nRF52832 chip. One of the GPIOs is used to monitor a 12V power supply. We use a voltage divider on the 12V so the...
