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.

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...
Hello,
I'm trying to get the new SDK up and running on my OSX machine. I would like to make the blinky example work on my PCA10003. So, I copied the blinky/pca10028 folder...
Hello, Do you guys know if it is possible to generate a stable 38kHz signal using the Nordic?
I have been able to generate the required frequency however I am observing...
Not a question but thought worth mentioning.

Hello,
I am working on an nRF51822 custom board application which is reading data from external sensor through TWI. It is based on the MPU6050 driver available in the SDK...
Hi there,
Before I asked this question, I have searched similar question about TWI example, but it seems there were some guys looking for such example as well. Not sure...
Hello
I try make a firmware update with nrf toolbox for iOS and i have a popup with "Please enable Service Changed Indication in your firmware".
In code, I have an error...
while I'm trying to compile my code, I got an error :

I wonder if GPIO could safely be used for byte writes to the OUT port.
I have an 8bit (+control signals) peripheral connected to the GPIO and so far I was doing read-modify...
I will be using a 3.7V LiPo to power my NRF52 system. As far I understand, using the internal DCDC regulator is a better choice as it can save power compared to internal LDO...
I am running the UART example with the S110 softdevice on nrf51822. Sometimes my application transmits more data than can be carried and backs up. So the main thread's transmitter...
Not really a question, but congratulations to Nordic on getting their chip onto the Micro:bit(is it the nRF51 or the new nRF52?). Looks like a cool device. I'll be hanging...
Hi,
I want to change the device name before advertising. But it looks like I cannot open the adv pipe.
I have set writeable device name both from air and from application...
