Hello,
I'm looking for answers and some explanation for two main questions - is it possible to perform non-simultaneous multi-image FOTA over WiFi? Is it possible to support...
Hi,
I am wanting to talk to this external 1Mbit RAM chip through an SPI interface: https://www.microchip.com/en-us/product/23lc1024 with the nRF5340 device. Preferably,...
Hi
It seems that the default minium DTLS handshake timeout is about 1 second. That means, there is a retransmission if a response isn't received within this timeout. In...
We have the HCI DFU working. The PC sends the new hex image (python script) via UART to nRF51822. Therefore, the bootloader code on the nRF51822 works. However, in the final...
Hi,
i'm using s130 central/peripheral. I want to send data from my central nrf51822 to my peripheral nrf51822.
I declare write function like this:
