Hi, p0.06 is always high lever when the following codes are executed:
nrf_gpio_cfg_output(6); nrf_gpio_pin_clear(6);
Why?
Softdevice is used in the project.
I have searched through the examples and the documentation (BTW the online document links are broken - the offline documentation is nice however).
From what I can tell...
Hello Everyone.
I am doing a project where I need to do a Bluetooth communication of data. I have two nRF51 DK so the idea is to connect a particular pressure sensor to...
I am trying to create a state machine that will be able to turn the Bluetooth radio on/off and possibly change the mode of the BLE service for power testing. I hope to run...
