Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:

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...
I thought I had been extremely careful to _not_ brick the device, but apparently I did.
I created a firmware-dfu.zip file, even with appropriate keys, etc. as below.

Previously, I designed a PCB for the nRF52832 chip using the RFANT3216120A5T antenna ( link ). However, I was only able to achieve a very limited Bluetooth range of around...
Hi Nordic teams :
I find that datasheet v0.8 (page12) shows that SDA do not need clock.
Page 277 still shows that SDA need clock pin.
Could you help to clarify which...
Hi, I previously wrote about an unexpected behaviour which I've made a diagram for below. It's relatively simple though, the COMP watches a voltage and fires a toggle event...
