Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
Hello,
I need time synchronization between the two devices. At the same time I want to use the standard means of bluetooth, synchronizing the clock of the connected devices...
Hello,
This is the first time I try to implement DFU to update my simple application OAT via BLE on the nRF51 DK.
My simple application is a simple peripheral which...
I have a GPS over UART to a nrf5283. For debugging the GPS, I'd like to passthrough UART from my PC to the GPS. I know the nrf5283 only has one UART. Is there a simple way...
First about my setup: custom devices with NRF52832 chips (SoftDevice 132 v.4.0.2), android smartphones Nexus 5x and 6p.
I'm trying to connect as many BLE devices (peripherals...
I'm working on a custom board with an nRF52382 connected to an IMU over I2C. The IMU provides 2 separate interrupt signals, and I would like to route each of them to a separate...
Hello,
Today I've a strange behavior of nRF51 DK (everything was working ok until today, the last things I did was to reset the J-link FW after a total erase of the board...
