transmission current

[Kaito]

hello Now i am useing the DK of nRF52832 and SDK14.0.0 of ble_app_uart. I am experimenting to transmit data from external equipment to nRF 52832 and send data to smartphone from there.

The picture is shown in below. gyazo.com/9a3bc4b48b031475e6d5dbd3180c2c9b gyazo.com/3e2439256828457b4a2403d3e24832eb gyazo.com/61028a1bd83f6fb8c2e0c5d879cbbff8

Is this the transmission current surrounded by this circle? Since a 10 Ω resistor is placed, only about 1 mA of transmit current is flowing. At this time, data transmission is successful.

Thank you in advanced.

Yes, this looks like the BLE transmission. 1 mA is a too low, but the resolution on your equipment is probably not good enough to show the peak current. You can have a look here to see the BLE transmission current: devzone.nordicsemi.com/.../
