  • Is the UART 3.3V TTL compatible?

  • I was using TMobile prepaid broadband and it wasnt working. After about an hour of troublshooting with a very helpful guy at the TMobile store we were able to get it working. I switched to the month-to-month Blackberry unlimited data plan. The problem with the prepaid broadband is that its meant for a USB dongle that expects config info from a PC. We tried pay as you go and that doesnt usually have direct access to the internet (it goes through web2go.com, a tmobile proxy). The blackberry data plan is essentially a smartphone plan without the phone capabilities, which is a perfect fit for this device if your looking for data only capabilities.
    Hope this info might help someone

  • Make sure you have your terminal program append each command with CR or CRLF otherwise the device wont respond to the command.
    This drove me nuts for about an hour and then I saw AT reference a command postfixed with CR. I had my terminal appending LF. I changed it and problem solved!
