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...

Hi,
I need to send an audio signal through BLE connection of nRF51822 module, this signal need to quantized and sampled at rate of minimum 8000 sample/second by ADC, i...
I would like a working example of a simple application that uses soft_device (either S110 or S120) plus UART debugging.
I have read many posts in this forum about this topic...
Hi folks,
do you supply a BT Test-SW to set a module with your NRF51822 in different test modes like continuous FH etc. or to change the device to low, mid, high channel...
Hi,
I want to establish a peer-to-peer communication network between 2 nRF51422, such that both the nRF51422 can Transmit as well as Receive data. Is it possible to achieve...
hi,
as we know, the device need to being linked in 1.28s if Advertising types is BLE_GAP_ADV_TYPE_ADV_DIRECT_IND ,but my host can't link device in 1.28s,so i want to link...
Hi,
I try to evaluate DFU using serial but found difficulty. Seeking help here.
I use PCA10028. First, i falsh S110, v8.0 into it.
Then, compile SDK8.0.0\examples...
Hi all!
I want to allow only 1 device to bond at a time. If another device bonding, I want to delete the previously bonded one.
I tried to use dm_device_delete_all() in...
Hi all,
I'm trying to get TWI working on the nRF51 DK but it's not working.
I used the twi_hw_master_sd.c file so softdevice use should not be a problem.
When I debug...
I am using internal ADC to sample 2 (sometimes 3) channels on about 333Hz frequency.
What I do is:
set channel 1 as input (always two-thirds prescaling, VBG reference...
Hi,
I want to debug nrf51822 beacon using DK.I made the necessary connections between dk and beacon.I managed to flash the beacon using nrfgoStudio , but if I want to do...
I have the following code, it's pretty bare in terms of its functionality:
#include <stdint.h>

I succeeded to made the BLE DFU example of SDK 8(bootloader\pca10028\dual_bank_ble_s110) with softDevice 8 working on PCA10001.
Now I want to try DFU over UART.
I follow...
