I have not used pyserial but based on the API documentation at https   pyserial readthedocs io en latest shortintro html it seems like a very nice interface   It might be worth double-checking the specification for AT commands of the device radio whatever you are dealing with   Specifically  some require some period of silence before and or after the AT command for it to enter into command mode   I have encountered some which do not like reads of the response without some delay first
