LTE & Lora/Sigfox Antennas
I read in the documentation that you must attach the antennas when using LTE, Lora and Sigfox.
The questions are:
- Is it realy safe to turn the board on without the antennas when using only the Wifi or BLE radio?
- When does the LTE or Lora/Sigfox antennas are really necessary? When are the radios tuned on and off? Is there a command for that?
Thanks in advance.
