I’m trying to get a RAK3272S to work. I have hooked it up to 3.3V of a bench power supply. The UART is connected to a FTDI TTL-232R-RPi.
The module doesn’t take any current. Also double-checked with a Fluke Multimeter. Is this normal? Also, sending it AT commands via RAK SERIAL PORT TOOL doesn’t do anything.
I have also tried to pull BOOT0 to high/low. Doesn’t change anything to the current.
The same applies to the RST Pin.
Do I have a wiring issue? Or did I maybe receive a faulty module?
