AT#STARTMODESCR would be a good place to start.

Get yourself a copy of RSTERM from www.roundsolutions.com/techdocs

Hope this helps.

Flow control should be used if possible. The RTS / CTS lines can be tied if required.

Just took a quick look, the device is dual function. Bluetooth and serial. The SPP relates to the bluetooth part which you can pretty much use with any BT laptop/PDA or phone. The Micro USB is supplying serial at cmos level so you with have convert to what ever interface you require after you have f...

The forum might come across as a bit harsh not replying but you are asking for quite a bit of help. The eval kit would be fine to get you started and with the addition of a button you could do what you want. There is however a little more to it than that. YOU will have to read all of the relevant do...

AT+CMGL to list SMS AT+CMGR to read SMS AT+CMGD to delete SMS You will find lots of AT commands in the manual to do exactly what you require.

You will have to refer to your antenna data sheet for tuning methods.

Normal setup is Antenna - LNA - GE863.

Sorry I may have confussed you a bit. If you are using a Chip antenna directly on the board then there will be no connector. Chances are you will still have to have the micro strip on the board. You will also have to tune the antenna - you need to have a good read of the data sheet. You can also reg...

Dont forget we are talking about 50ohm impedance. NOT RESISTANCE. If you were to connect the coax from your antenna to the PCB then you should have designed a 50ohm micro strip into the board. OR have a ufl or mmx....... on the board. If you have neither then you can put a connector in the coax. A f...

The patch antenna always give problems but its normally down to your 50ohm micro strip on your board. Dont have one? Then you have to use a 50ohm connector on the board or in the cable. However I use the Sarantel helical antenna which has the 50ohm impedance built in and gives by far the best result...

Leon is right, if the connection is not made correctly then you can't get the data to the GSM\Python part of the device.

If you are unable to access the pads/tracks your only option is to pilot drill through the pads and cut the tracks. Then make your connections with wire.

Can you not keep the connection alive and just post as required.

As an example I have one application posting every 10sec with 150bytes with no problems (GPRS signal strength gives issues).

You could use projection, with an accelerometer fitted. You would also need an MCU etc.

What is the application, why do you need the data so often?

I have seen a few threads on the roundsolutions (Dec 2007) forum saying that they now have a solution, however you will have to email them to get the answer.
