Often, a packet will be “successfully” sent by my BK7020E, but not received by T-Mobile or my endpoint. In my ESP32, I simply get an OK back from my SIM and nothing shows up in the portal or my server. Is there any way to get a response back to my module so it knows if the packet has arrived? (From T-mobile for example)
This is a problem I’ve been having for a couple of months now. I’m catching errors and other messages from the BK7020 and retrying when necessary, but like I said, there’s still a lot of OK’s that don’t arrive. I simply have no idea if a packet has been successfully sent or not.
With kind regards,
