Hi, I wanted to ask a question regarding sending data.
I currently have external memory that will send out serial data (SPI) to the nordic microcontroller. I have saved...
Recently, I try to programme nRF51822 DK communicating with nRF2401e1 DK,unfortunately，which does not success. With setting radio configuration: TXPower,frequency channel...

I have been trying to understand and get the “ble_app_template” running this weekend, but I keep running into errors. For example in
static void sys_evt_dispatch(uint32_t...
Based on the nRFUart demo, I added a masterEmulator.DiscoverServices() block before the DiscoverPipes() block in a very similar manner. Purposed is to be able to get more...
Hi,
There is much talking about the "large data transfer" over BLE, the l2cap channel being the best option for the moment.
However, does anyone know the datarate achievable...
I am developing a power aware TWI driver for 51822/422. All appears to work properly except when I simulate a bus fault by shorting SCL to ground or shorting SCL and SDA together...
Hi,
Firstly a warning I'm a noob in this area.
I'm seeing some strange events consistently returned from the nRF8001 over SPI. I have an example of the SPI traffic below...
Hi! I would like to get adc sample from two different channels at the same time on my beacon (nrf1822), using the same interrupt. Is that possible?I mean I can use ADC_IRQhandler...
Hi,
It's a very simple question, is there a simple way to check GPIO pin status. I just want to know at a given time if the Pin is High/Low. I don't think I need an ISR...
Hi, I just started working on nRF52 with Bluetooth, and I have some concerns about DFU and security.
I’m working on a product equipped with an nRF52 and a MEMS microphone...
Hi!
I am using the NUS service and I noticed that Android 6 (Marshmallow) will not go faster that 47.5 ms. Even iOS can go to 30ms. My target is 7.5.
Am I doing something...
Hello,
I am using nRF52832 with S132 and SDK_11.0.0. I am facing issue with using power fail warning POFWARN. below is my code snap.

Hi All.
I'd like to know how to turn off or on shockburst feature.
After I set auto ack & retry count, Tx successful interrupt occurs, even though receiver device is in...
I'm migrating an app from SDK8 to SDK11 and I'm getting errors using TWI to communicate with my IMU (Invensense 9250). I first tried it on a nRF52 DK (Eng B) and then went...
I've either got a bug in my code or the JLINK connection is dying. Either way it's a real headache to pinpoint and discover how to resolve. Knowing more about extracting info...
Hi, Now I use the NRF51822 ADC to sample VCC , 1.2V internal reference，internal prescaling 1/3.The PCB connection show as the pictrue .My application develop base on soft...
Hi,
I would like to make some measurements via I2C in radio_notification_evt_handler. Unfortunately, after executing a random number of measurements, the advertising stops...
I'm trying to make a BLE device that actually pairs securely. I posted this question on StackOverflow but didn't get any answers - maybe someone here knows more. As far as...
Hi,
I am wondering which frequency tolerance is acceptable for the HFXO, as in the product specification, p.105, a maximum value of +/- 40 ppm for Bluetooth low energy...
