Hi PJ,
Thanks for your tips. I can do that, but it is unlikely that the GND is floating.
About the trying to transmit you said, this is also not the case since when starting up the fw does not send a message.
When transmitting it should be around 26mA for the low energy chip when the power output is 14dBm.
But, I agree that it seems like something is floating here, but then it would be internally in the chip.
I’m using an OTII power supply to check the current consumption.
Best regards,
Vinicius
