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...

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...
In connection with a nRF51422 evaluation kit, I installed the Keil development tool in a non default path then subsequent installation of nrf51_sdk_v4_3_0_27417 produced a...
How does the nRF8001 chip generate the passkey in the DisplayKeyEvent? Is it possible to set this passkey from the App Controller?
As I understand it, the SetKey command...
I find this strange but I can program the HRM demo fine but with my own code it compiles with no errors or warnings but will not program with Error: Flash Download failed...
Hi Nordic,
I want to develop a PC software that works as a master device which can scan for advertising packet, establish connection, etc. Basically, something similar...
Dear Sir,
After I remark this //BLE_GAP_CONN_SEC_MODE_SET_OPEN(&cccd_md.write_perm); and program it into nRF51822, then I cannot program it again. PC program report it...
I have modified the included HID mouse example to allow for left/right/middle mouse clicks. However, it is not clear to me how to set an event handler for both when a button...
What is the recommended PCB thickness of the nRF51822-QFAA Reference Layout? It'd be great to have a specification in the package including the full spec of the PCB material...
Hello Folks, I'm starting some work with the nRF51822 Evaluation Kit (PCA10001), but have very quickly run into a blocker when trying one of the ble samples. (I've previously...
With Soft Device 5.1.0 I generated the binaries from the hex by doing:
arm-none-eabi-objcopy -Iihex -Obinary --remove-section .sec1 --remove-section .sec2 s110_nrf51822_5...
Dear support,
We are in the design stage for a BLE application. We looked at different options. Although the NRF51822 seems better in specs. The TI parts CCxx offer this...
So far I have made a successful program that utilizes BLE to send and receive radio signals in Kiel. But I have only been testing this program by using the provided Master...
I just entered a Case to Nordic with this same question but do not expect to get a response over the weekend so I am posting here. I made the assumption that the Nordic Cases...
Dear everyone:
Now,I have a project which use Nordic product solution to developemnt.
And , We need your company to provide some information and solution.
