Hello,

I have some problems sending SMS via the GSM EB066-01-Module.

I am using Flowcode v4.5.18.74. The used chip is a 18F4455. The oscillator frequency is 4 MHz.

The board is correctly connecting to the network. I can call the board and the return value 2 is given for an incoming call. But there is no value 1 for incoming sms. Otherwise I am not able to send SMS. Calling the macro leads to a return value 255.

I have attached my testfile.

Could you please give me a hint?

Best regards

Simon Stockhorst

Hello Simon,

My advice would be to perform a 1 second flasher test as I'm not sure if your configuration settings are correct. This should help to confirm if your serial baud rates are also correct.

Hello Ben,

I tested the led flasher and everything works fine. I use several e-blocks with serial communication like (rfid EB052, gps eb056, tft with touchscreen EB076) connected to Port C and got them working. I wonder why a call is recognized and SMS not.

Could it be a problem with our prepaid card? I got the board working with another card three years ago. http://www.matrixtsl.com/mmforums/viewt ... b1124101f4

Thanks in advance.
