I am developing hardware for the nRF52840. After testing our firmware, we are going to need somewhere around 6,000-7,000 mAh to run our hardware for the time needed. We were...
Hi, all.
I used sd_ble_gap_addr_get() function to get a MAC address in the different example and the result was different.
I tested this example in SDK v14.2 and v15...

Do nRF8001 chip has its own internal linear regulator? or Does it need an external like the module created by Adafruit ( https://cdn-learn.adafruit.com/assets/assets/000/035...
Good evening all,
I'm trying to get my DK52 communicating with a CR95HF (this is a NFC controller with serial and SPI control interfaces), I'm using a breakout board - BM019...
Hi Sir, I use load switch circuit to control nrf8001's power. I found even the vcc of nrf8001 is empty, nrf8001 still works. That's not my expected result, I think nrf8001...
Hi ,
We know that the nRF8001 use the random static device address . I have the questions below :
A. Will the device get one new address after power on ? or is the address...
