Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
I have tried ble_app_uart_c project in SDk 9 , SDK 10 or SDK11 , but they have the same problem.
Problem is that slave(SDk 9,ble_app_uart) can send data to master(by terminal...
While trying to bond an iPhone 6 (running nRF MCP App) with an nRF52 with S132 2.0.0 I encountered the following error:
On the first try, when the iPhone is not yet paired...
I am trying to set up a button interrupt by adding the following functions:
void button_interrupt_handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)

Dear Sir,
When nRF51822 is a slave, it should be updated software through Master(Z-Wave CPU) remotely.
How can we update SoftDevice software in nRF51822? UART, SPI, or...
My code detects an external signal using GPIOTE. Whenever the signal falls, GPIOTE calls a handler, audio_stimulus_handler . The code is shown below. Essentially, after detecting...
I have a nrf51-dk. I would like to the pincode to be stored in some configuration settings which is written in non-volatile memory. I do not want the pincode to be hard-coded...
I want to place a IoT application on an Application chip and connect it to a Connectivity chip running the BLE IoT SoftDevice.
Does the nRF5 IoT SDK support serialization...
Hi Guys,
I know this is more for software issues. But I was curious as to where I can find trusted case providers/makers for the nrf51822 Beacon. Can anyone from the community...
Hi,
I am coding a Sharp memory LCD display using SPI and the nRF51422 development board.
I have tested the SPI connection using a logic analyzer and signals are being...
I will start doing a custom PCB (1.3cm diameter) with a nordic BLE, any recommendations about the components needed and design?. I need to use mbed programing tools, any experience...
Hi,
After training on a PCA10028, i want to develop on my personal board.
I use keil but i saw a problem.
The libraries are all in folders of folders in the sdk folder...
I don't know why I didn't notice this blurb in the reference manual sooner. In pretty much all peripheral sections (such as SPI), you have this warning:
Therefore, the...
