I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
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.

Hey everyone.,
I was trying to use nrf51822 as spi slave and just a heads up to know that i use Nrf51822 as master. I see that when chip select CS gets low SPI needs to acquire...
I've added a custom service and a few characteristics on the nRF51822. How can I access the current value stored in one of those characteristic outside of a BLE event occurring...
Hi,
I'm unable to run any application on nrf51 DK (Keil used). When I start debug (no matter what application I load), program always cycles between 2 instructions:

Hi,
My application uses the softdevice 110.
Everytime, there is an event on my sensor. The sensor sends the event to my pin, which generates a gpiote interrupt . But, the...
Hi,
I'm trying to determine why a HCI DFU upload fails.
There is a log of the communication below showing the serial request/responses on the Windows side.
Is anyone...
Hi: I use dfu_single_bank_hci to update application. HCI_SLIP_UART_MODE = APP_UART_FLOW_CONTROL_DISABLED, HCI_SLIP_UART_BAUDRATE = 38400.

Hello,
In my quest of working with pstorage_raw.c I found an annoying situation when I tried to clear small portions (as I thought by using raw I would have full control...
Hello!
I have based myself on the ble_app_uart example, taken out the UART bit, and all that remains is the bluetooth functionality.
I have also implemented SPI communication...
hi guys, :)
I used SDK 6.1.0., Softdevice version is S110_nRF51822_7.0.0.
I compiled the template project. (in the "C:\Keil_v5\ARM\Device\Nordic\nrf51822\Board\nrf6310...
I want to use the UART to get and send data to another MCU on ble_app_beacon of SDK 8.1.0.
But after I add the UART function to the project, the UART can't work.
Can the...
Thanks for the SDK 8.1.1 fix. Please make it available also as a .zip in developer.nordicsemi.com/.../
Currently the fix cannot be used with a GCC toolchain as it is only...
Hi,my friend
I use the nrf905,At one end Use the PCB antenna, on the outside part of the metal.Using the results, said communication distance is shorter than 40 meters, easy...
Hi,my friend,
I have been using nrf905, but its performance is very bad.
