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.

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.
...
I need to connect an I2C/TWI device to the nRF51822. The I2C device is running at a fixed 3.3V (from a boost DC/DC), but the nRF51822 is powered directly from a CR2032 battery...
Hi,
Is there anyway to keep the RTC going while in reset, device sw has crasched or in powered off mode or would I need an external RTC for this?
Is there any possibility...
I have two NRF24L01+ devices. My aim is to have one as PTX and the other as PRX replying with ACK_PAYLOAD. It is working with ACK enabled (without payload). However when ACK_PAYLOAD...
I'm interested in using the master emulator to connect to multiple target devices, but it does not appear there is support for this in the API (v2.1.3). For example, there...
I just discovered that the s110 SoftDevice does not support a peripheral connection and non-connection based broadcast. This is one of the primary specifications for my application...
What's the trick to using the WDT without causing a system reset???
We want to use the WDT for a pause mechanism - then continue from the pause at the same Main location...
Hi,
We have Nordic custom board. flashing simple c program to custom board is done fine.
cant able to get expected result. so we tried for step by step debugging. but...
Hi,
Is it possible to use button press(button on slave) as an authentication key to establish the connection. Since our device does not have an display or keyboard, we are...
Hello,
I've modified some of the gazelle sample code and I've been testing the throughput. I am basically using all the default settings and I'm seeing throughput of 43Kbps...
I try to ACK payload mode by nRF24L01+,but not work well. show me a typical config register setting.
My target is transmit 10bytes and ACK payload 5bytes, as soon as possible...
Hi,
This error happend when I tried to install nRF51 SDK(nrf51_sdk_v4_3_0_27417.msi). The step is that. First of all I installed keil-MDK4.72 and than I installed JlinkARM4...
Hi,
