Yes.
In Debug mode, “<” indicates data sent from the device to the server, like this…
which is a 1D hex (29 decimal) “BLYNK_CMD_HW_LOGIN” request, followed by your Auth token
and “>” indicates data received from the server, like this:
which in this case is a C8 hex (200 decimal) “BLYNK_SUCCESS” response message.
So in effect the device is asking the server for permission to log-in, with the Auth token as the credentials, and the server is responding with Okay.
