I am using the Freematic One (https://freematics.com/store/index.php?route=product/product&product_id=82) OBDII Dongle to read data from my Car. I then wish to use the Hologram SIM card to send data through the SIM3560 in the Freematic, to our server.
Unfortunately, I have ran across some problems.
Here is their config file here (APN starts at line 15ish). We replace it with:
define APN "hologram"
define SERVER_URL "our IP address"
define SERVER_PORT 8081
--- Deleted #define SERVER_KEY "TEST_SERVER_KEY"
However, we keep getting errors (with no clear error message) on our Freematic. Any help?
Edit: After further use, the APN isn't connecting for some reason.
