    Hi,

    I am using sim800l to test and when connecting to the at command tester and then clicking on ‘Find port’. It is successfully detecting the port. But when I am clicking on ‘Connect’ , it is checking for all the baud rates one by one but failing for all. Atlast throwing error as ‘invalid or no response from the device’ . What can I do for this? Please suggest.
