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.

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...
Hi,
Some questions in example ble_app_hids_keyboard/main.c
Why set the adv_params.timeout to zero in BLE_DIRECT_ADV (Line 779) ?
That will cause no BLE_GAP_EVT_TIMEOUT...
I just got a nRF51 and am having trouble getting started with it. I created a very simple program using the mbed compiler and produced a hex file which I now wish to flash...
Hello,
I see that the make files that have been included have provision to remove dead code from the projects to reduce code food print. This is accomplished using the...
HI folks,
I have checked the current consumption while connected on an average to be 325uA (with uC taking 4.5uA) so this mean almost 320uA being consumed by the nrf8001...
I have a general question about the RF frequency tolerance of Nordic devices in general. Is the following calculation correct?
Crystal spec = 16MHz, +/-50ppm tolerance...
Are there any plans to add boundary scan functionality to assist ICT testing? If not, are there any other hooks into the part that can be used to test during ICT?
Hello
I'm using a pstorage_register from pstorage.c to register two application storage blocks in flash memory. But I have situation that first module have 6 blocks of...
Hi,
are the GPIO pins broken out on the nRF51 Dongle configurable and can be used for SPI Slave tests? I have a running system powered by a ARM Cortex 4 (Teensy 3.1) and...
We have an early implementation of the v6 SDK DFU ported to support S310 on a handful of devices in the field and need to update them to a new bootloader and we'd like to...
Hi,
With the validation of the BLE V4.2 specification will Nordic be implementing the new features of the spec and if so do you have any idea of availability and dates. ...

Hello Everyone,
I want to start working on nRF51822 development kit for my project. but as mentioned on this site : www.nordicsemi.com/.../nRF51822-Development-Kit
that...
Hello there,
I am using the experimental_ble_app_uart with S110 on nRF51-dk and receiving sensor data via 1MHz SPI every time the timer ticks = 100ms.
Data transfer displayed...
Hey,
I created a custom PCB with the nrf51822 that reads two sensors via TWI and transmits certain data over BLE. I can program the chip, print strings to the terminal...
