Connecting to - SIM900a+Arduino problem


I tried TinyGSM_SIM800_SIM900 example. At first it connects to the cloud and for a moment I can see the connection on my Blynk app. After receaving a message: Ready (ping: 708ms) the connection stops and it keeps connecting (picture below). Any idea for that problem?


That’s quite a a long ping time. Anything you can do to improve it? (Different SIM, locating to somewhere with a better signal)?

You aren’t doing anything silly in your code immediately after connecting to Blynk are you, like a Blynk.syncAll?


I changed the SIM with another provider and now it works. Thank you!

ping time is still in a range of 600-700ms. I will check if I can improve the code.
