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...
I have an advertising device (NRF52DK+SD132_V3.1.0+SDK_12.2.0) where I whitelisted an address corresponding to my NRF51 Dongle (0xDA509C569622).
While the dongle is initiating...
Hi, At the moment I am using nRF Toolbox to upload DFU *.zip files to our devices. We have been finding that the devices will become unresponsive after a firmware upload,...
Hi!
I have trouble in flashing a simple nrf51822 via the nrf51-dk.
Can anyone ensure me that this simple wiring should be able to upload an hex file onto the nrf51822...
The Peer Manager is currently in experimental state and is not recommended for production and same for the device manager for some sdk.So which SDK should be preferred
