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...
Hi,
I am a EE with a lot of background in nRF52 devices. But this is my first software venture with this device. I am familiar with the soft stacks used and have flashed...
Hi!
We develop our product on nRF52840 using S113 softdevice, version 7.0.1. From time to time, we need to erase some part of flash, so we use sd_flash_page_erase() function...
