Hi,all.
I am using nRF52832.
Does the nRF52832 support dual mode that allows simultaneous advertising and scanning?
Are there any examples you can refer to if you...
Hi I use SDK 12.3 and sdk 2.0.1 , and set a device name length is 21 like "1234567890ABCDEFGHIJK" by sd_ble_gap_device_name_set;

Hi,
we are developing and application on iOS which can among others, update our hardware over the air, and we found out that e.g. after bootloader update is done, then...
Our hardware has an externa memory connected to the nRF51 by SPI, we also use DFU to update the firmware creating the zip pack (We have buttonless dfu working as well) and...
I've been using the nRF52832 chip for over a year and it works great. However, for a new project I designed a board so that the nRF52 chip was the slave on a SPI bus, and...
Hi,
I just try DFU function in sd130/sdk12.3 and it does work very well.
I did:
(1).Generating your own key:
nrfutil.exe keys generate priv.pem
(2).Display a public...
In the example code, I found this:
#define SERVER_COUNT (3)
#define CLIENT_COUNT (SERVER_COUNT + 1)
I'm having 2 boards (maybe extremely problematic) and I want to...
I have seen at least one person here who has gotten Nordic's UART-over-BLE example app running on the nRF8001. How was that done? Where is it? This example app is not included...
Screenshot of what I'm doing:
So I reset the nRF8001, then try to initiate a transfer by pulling REQN low. However, nRF8001 never responds by pulling RDYN low. I have...
