Hi,
My nrf9160-DK version is PCA10090, 1.1.3, 2023.31
I am trying to test the esim, but the firmware tells me no simcard found. After doublechecking the esim soldering, I think it might be something wrong with the DK board itself.
If I am using the default asset tracker firmware and physical simcard, no problem to let it run, P30 voltage is 1.8V. But if I plugout the physical simcard, switch the SW7 to eSIM, U20 Pin8 and P30 will keep 1.8V for around 2s and then become 0V. If I keep the setup as it is right now and turn off the DK power and turn on again, the P30 and U20 Pin8 voltage will always be 0V.
Why?
Best
