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,

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...
Hi, I try to connect nrf51822 and use example "ble_app_hids_mouse". I can pair this device and I confirmed that "Notify" becomes automatic at that time in Enable.
But, when...
Hello,

I'm trying to understand an existing example.
in this example after sending set up commands generated by nrfgo studio , program sends 9 byte of 0xff command...
I downloaded central and peripheral ble UART and I want to add some function to my code and use some GPIO, I programmed nrf51822 by nrf51422 source code and it worked, but...
hi there!
i'm struggling with the problem about using i2c with IoT SDK.
my project is about transferring sensor data (i2c) through ipv6 over ble , so i used the IoT softdevice...
I'm considering purchasing a nrf51 sniffer USB dongle. I believe I can use this to sniff beacon packets and with wireshark view the packet internals, data, channel number...
Hi
I tried to flash the softdevice with nrfprog, but it does not work. Even with nRFgoStudio it does not work.But with IAR I can program an example of the SDK (without...
Hello, all
I have a problem with ble data exchanging.
I have programmed an application which controls servo motors through phone application.
At the connection, ble...
Hi,
I am trying to use the SAADC to periodically sample an input from AIN0 and send the resultant data over a BLE link to a phone. Going through the forums I saw that the...
Hi,
I am trying to debug the blinky example project on the nRF52 development kit.
I have followed the following tutorial: devzone.nordicsemi.com/.../
