What’s new in July

We ended June having brought our new Gold G2 2-Button Intercom into full production and having restocked our old 1-Button internal aerial unit.

We have a new PCB which will form the basis of all of our dialers and gate/shutter openers going forward.  It features an ultra-low power mode, more inputs and outputs, space for a voice unit and Bluetooth.  The chip on the PCB has a larger program memory (like the hard drive of a PCB) giving us space to add more features.  The power supply design is more rugged too allowing for higher voltages and better surge protection.

We’ve finally given up on the Circuit Switched Data (CSD) system we used for remotely connecting to devices in the field and have revised the software to use the GPRS packet data system.  We chose CSD as it meant your SIM did not require data and there was no need to tell the GSM unit your network’s APN (Access Point Name) e.g. giffgaff.com…  The problem is CSD does not really work at all never mind reliably.  Quectel have dropped support on the new modems we are using so it was time to switch to GPRS.

We’ll be using GPRS to dial in in future

There are huge benefits though.  The newer PCBs including our Gold G2 Intercom can have a full firmware update over the internet using GPRS.  We have also added the ability for the dialers and gate openers to send emails whenever activity is detected.  Eventually we will either offer our software to the end user or create a web interface for setup to be done online.

    Can I expect the GPRS auto dialer to work with AT&T or Verizon in the central United States and when can I order the new GPRS style board? When could I expect to receive it?
