Hi,
I have a serious problem, when I use uart of NRF51822 QFAAC0 to receive data from another MCU, I found that it will lost one bit at same position everytime. my SDK is...
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...
Hi all,
My configuration:

Hi to everyone!
I'm following this guide to learn how to use secure DFU on a nRF52832DK board.
All steps have been done successfully, or I think so, until I reach the...
I want to find the agent of China, please, thanks
About Bluetooth and 2.4G, nRF52840/nRF52832/nRF52810
(The agent can provide some technical support and sales)
Can someone please explain the below line mentioned in NRF5 Serial port abstraction layer documentation.
Do not use synchronous API (timeout_ms
