However, according to the SIM of Japan · APN (iijmio.jp) · USERNAME (moi @ iij) · PASSWORD (ij) It is not possible to change them.

Please tell me how to confirm it to change them.

You should be able to pass the apn, username and password as arguments to the connect function.

gprs connect

modem.connect("iijmio.jp", "moi @ iij", "ij")

You likely also need a 3G(LISA-U) modem.

Thank you for the quick response.

Thank you for the quick response.

I bought a C027-U20. I am trying to assess the LISA-U200.

Correct the Main function, ret = modem.connect ("iijmio.jp", "moi @ iij", "iij"); / / eventaully set another apn here

I tried, but I did not go well, we have a question.

I think if you need to change to GPRS connection. However, I do not know where you want to change.

It safe by using the UbloxSerModem? We must change the case of UbloxUSBGSMModem.cpp? I tried to follow in various ways, but I'm lost.

Will you tell me? I need your help please.

I do not know about all the details in the cellular driver from mbed_official that is being used. Maybe you can try Debugging the individual AT commands. The C027_ModemTransparentSerial example will give you access to the serial interface on the mbed serial. You can then send AT individual commands to the device with a simple terminal like putty or teraterm. Use the AT command manual from the modem suppliers web site and type individual commands. .
