Quantity tries connecting to host/ip #541

Closed yaroshd81 closed 3 years ago

yaroshd81 commented 3 years ago

Where is the number of try to connect to the given host(ip) is indicated?

yaroshd81 commented 3 years ago

I know, what 20 tries connecting, but i can't find this variable or constant

SRGDamia1 commented 3 years ago

Usually it's just one.

yaroshd81 commented 3 years ago

Ok, but where this variable/constant? What is name variable/constant??? I can't find it.

SRGDamia1 commented 3 years ago

There is no variable or constant defining how many retries to make on a connection. The client.connect(...) function passes off to the modemConnect(...) function which uses appropriate AT commands to open a TCP connection and then returns true/false based on whether the modem reported success or failure. There isn't any retrying involved unless you've written that into your own code. If the modem itself attempts a connection multiple times before returning a response, that's part of the modem's built in firmware, nothing this library does.

SRGDamia1 commented 3 years ago

One retry. No variable or constant. Just 1.

Ok, but after command:

mqtt_.connect

An attempt to connect takes 40 seconds, which is a very long time. And makes 20 identical requests (except for the initial one)

yaroshd81 commented 3 years ago

40 sec, because not pay. If paid - connecting the very fast, but we can have situation, when don't pay internet on our sim-card. (sorry for my bad english - i learn germany). Example for this situation, when no money: no internet, but sim-card active and GPRS connected.

yaroshd81 commented 3 years ago

I'm find it, sorry
