We are building a sollution using nRF52832. Using the UART over BLE application example as a base we managed to add DFU capabilities to the application etc.
Right now I...
Dear NRF community and support This is a followup question to the DevZone post https://devzone.nordicsemi.com/f/nordic-q-a/2860/flashing-bootloader-and-application-via-j-link...
From everything I know and understand of the system architecture, this shouldn't be possible, but one of our early production units out in the fields has twice now apparently...
I'm designing a two-part computer input device: Part A will communicate with the computer over BLE, but it must also be able to forward along messages from Part B. Here's...
Hi,
I am trying to update the MTU between the central and peripheral to the maximum MTU.
at the connection interrupt from the central side I added
