Hi,
we have a nrf51 mounted inside an AC motor housing which we assume is causing an unintended flash erase from time to time (checked with nrfjprog --readcode).
Is...
Hi,
We have a custom board with a Telit Bluetooth module, Bluemod+s42, now.
At present, I am using the "nRF Mesh" APP to test the feature of proxy. But, I encountered...
