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...

I have been trying to find a document referenced here 1 .
The reference reads as follows:
For more information on both modes, see sd_app_evt_wait and the nRF5 Series...
Hello there,
Finally received my 2 DK's after developing my other 2 custom PCBs and not knowing how to program them without the arduino IDE and now I'm struggling to program...
There seems to be a bit over a bug with the freeRTOS example. If you add the Scheduler to the BLE thread, Scheduler events will always be one event behind as there are only...
