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 am having an interesting issue trying to send packets. Only a very small number are being received (~1 per second even when transmitting one after another), and they are...
I want to use a UICR for device serial number. Correct me if I am wrong but it is my understanding that a UICR cannot be changed programmatically like onboard flash can. So...
I'm using the UART to talk to a GSM modem. It has hardware flow control and supports a baud rate of 115200. I'm using app_uart_fifo.c, not app_uart.c. I'm using the SoftDevice...
Hi,
Does Nordic Semiconductor provide any resources (codes, macros, documents) for work with IAR or Keil's simulator to fully simulate nRF51822's peripherals?
Thanks...
Hi,
I do:
err_code = ble_bondmngr_bonded_centrals_delete();
APP_ERROR_CHECK(err_code);
till now all is ok.
But when I do:
err_code = ble_bondmngr_whitelist_get...
Hi,
I need to delete all centrals using ble_bondmngr_bonded_centrals_delete ble_bondmngr.c function. It is working but it is not cleaning the whitelist.
So, when I do...
In the example of hid_mouse, ble device will bond master when disconnect event happen.
I try to add this two codes to Implement my idea.
err_code = ble_bondmngr_bonded_masters_store...
I write this code to set my ble device power down,but it causes reboot without any error report.

I try to use 51822 to run ANCS sample(ble_app_ancs). It work well and I can get notification source and notification attributes. But I don't see any source code for get App...
Hi
I've a reproducable behavior i'm not able to explain. I'm using the softdevice S110 6.0 on a nRF51822.
The firmware implements some BLE profiles and uses TWI Master...
Is there a way to map external memory (SPI connected) to force the app to start execution from there ?
If not feasable , there is a way to transfer the execution from internal...
I have a 51422 board design and I just got Ant-FS working with our firmware so I can now download data from an external SPI flash to a desktop application.
I want to be...
Hello:
I am using NRF51822 to design somethings. And I want to use interrupt send method instead of polling send method.
NRF51822's UART0 provides TXDRDY interrupt. After...
Hi,
I have tested the nRF Toolbox proximity application using nrf51822 evaluation kit and with nexus4 smartphone it is working fine. Now my question is, is it possible to...
