BLE on seeed nRF52840 Sense doesn't work if its not powered by USB C

I am a beginner with the seeed nrf52840 sense device.

I am flashing a peripheral LED example using Arduino IDE and ArduinoBLE library.

The problem comes when I am powering the device with the battery or the VCC and GND pins and not with the USB-C directly to my computer. Then the BLE connection doesn’t work, and the device is not advertising or visible. It seems like the BLE communication is not enabled when it’s powered by a power supply instead of the USB-C connector and the computer.

I appreciate any help or ideas to solve this issue. Thank you.

Hi Jimmy,
So if your using the BAT +/- pads on the bottom , It works perfectly. Check out the pics in the Xiao threads,

Thank you for your answer. Yes, I connected directly with the battery. The problem was with my code reading some sensors. Fixed now; thanks for the fast answer and support.
