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.

Hi Devzone:
I have a question that may be common for companies distributing hardware containing nrf52840 chips.
I have figured out how to use nrfutil to generate Bootloader...
Hi there,
I connected my nRF5340 PDK to an external target - which was unluckily defective.
Since the external board had its own power supply, there was now either an...

I have flashed the devices with light-switch example application under nRF5 SDK for mesh V 4.0.0 on PCA10040 DK. I'm...
Hi,
I have a custom application running on a custom PCBA using the nRF52840 MCU. The Softdevice (S140, v7.0.1) is also utilised because the main application supports BLE...
Hi,
I am looking for the timing of when a connection event will happened. Radio Notification seems the right method for me since it provide an interrupt right before an...
I'm looking at the feasibility of using extended and/or periodic advertisements from an NRF52 to be received by a cell phone. I've used nRF Connect on a couple slightly older...
