Tips and questions relating to the GPS modules from SFE
By dymosol
I'm using a GM862-GPS to develop my product. I have it working with a microprocessor. It connects to a server using AT#SD. I'm having some serious speed issues. It takes over 30 seconds to do a transaction(connect, transfer data, disconnect).

The server is in use by other devices and is fast, and I'm only transferring about 10 bytes back and forth within a transaction. Just calling AT#SD and waiting for CONNECT takes well over 10 seconds.

Am I missing something here? Is there something I can do to speed this up? It shouldn't take over 10 seconds to create a socket and establish a remote connection.

Thanks in advance,

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).
