I am using an Ardunio Uno and a Botletics SIM7000 LTE shield. I modified a basic sketch that turns on an LED. I send a text to the device, it reads it, interprets it, and then lights the correspondong LED. It then sends a text back to me via Holgram. In Hologram, I have set up a route that forwrds the text to my cell phone.
So I send a text “Red” to the Arduino&shield, it lights the red LED, and sends a text back stating “The red LED is on”.
This worked very well, with about a 4 second round trip of the text messages. Recently, the return text takes minutes to arrive back.
Any ideas? did something get changed at Hologram?
