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...

Im triying to replace the original 3D imagen from Thingy 52 Android App, but always i replace it for another one, the apps Crash when i go to Motion menu...
I have been developing a program for the nRF51-DK that reads an input value from an analogue input pin and displays this on PuTTY(terminal emulator software) using the UART...
This is for the nRF51822.
I have done some tests where I configure a pin as input with pull up enabled and then reconfigure the pin for an adc measurement with 1/3 prescaler...
Hi,
Just wanted to point out that I noticed that after pressing Button 1 to put the device into connectable advertising mode, LED 3 turns on as expected. But if the connectable...
I want to make a PCB with the nRF51422 chip on it. Is there a way of programming it externally using the nRF51-DK? If so, what connections do I need between the PCB and the...
Hi all,
I am finding that the RTT Viewer is very unreliable at changing colour when sent commands from two different nRF52-DK boards. The text is coming out correctly,...
I'm trying to generate pulse oximetry service (PLX) with Bt. Dev. Stud. and NRF5 plugin. PLX Spot-check meas. and PLX featurees characteristics are generated pretty well and...
Greetings,
We've got a product which has a NRF51 device on it, which has since updated the design to NRF52. Both variants have a DFU feature.
For the NRF52 I can positively...
