we are using E-Series Modules with U-BLOX Module U201, that are supplied with 5V on VIN (via 24V DC-DC Converter).
Battery is not used.
Now i have some modules, that won´t connect wo the cloud, until i connect the USB additionally.
As soon as USB is connected, the Electron connects with 60% Signal strength on 2G.
I Measured the Voltage on VIN, and it is exactly 5V DC.
Are there some Software Settings for the PMIC or power configuration, that could cause this?
The PMIC settings are not changed in the software.
