Hello List,
I have an Arduino Nano 33 ble with nrf52840.
It is powered directly with 3.3 Volt using 7 Volt and a 3.3 Volt LDO voltage regulator.
It is programmed (via the bootloader) using nRF5_SDK_17.1.0_ddde560 software.
The program is basically an adapted version of examples/ble_periphiral/ble_app_uart.
At some point I want to turn the system off by using a command send to it via BLE.
Then sd_power_system_off() is called.
After turning power off (switch between 7 Volt and LDO) and then it on again, the system should boot and advertise itself, but it doesn't.
Only after using the reset button (RESETN of the NINA-B3X) on the Nano does it start properly.
Is the power cycle not seen as a proper reset?
How can I make it start properly in this scenario?
Thanks again, Sietse
