Hello,
What are all the supported cipher suites for the nrf9160? Per your documentation, it seems AES 128 is supported but not AES 256. But, based on some testing with slightly...
What is the thermal resistance for the following part number: nRF52832-QFAA-R
specifically the thermal resistance between the junction and the ambient in C/W
Dear Nordic,
we are developing DFU Secure bootloader for a nRF52832 based HW.
We are starting from the "\examples\dfu\secure_bootloader" . First of all, we succesfully...
Hi,
Actually in my program I have a serial uart interface that cause an interrupt when a message is receive. During the interrupt, I send a mesh model command and its works...
Here I use gpiote and Ble_template_example.
The advertisement code is working fine but now I use button interrupt to send different payload or the button press change...
My understanding is that secure boot calls an interface to make portion flash that contains a bootloader immutable. Since this is called after the bootloader start to run...
