Hello,

I am having a problem using the gsm module. After i program the MIAC, i have to switch off the MIAC then switch on for the gsm to work. After that, if i turn off the MIAC and then turn on again, gsm does not work. i have to program the MIAC again. I have tried this several times and its the only way the gsm works. The flowcode seems to be fine. can anyone help me?could there be any reason for this?

thanks
Regards.

Hi,

That sounds like some kind of timing issue. Are the MIAC and the GSM module powered from the same supply? You could try putting a delay at the start of the MIAC program, before you initialise the GSM module.

hi,

I am powering the gsm module from the miac V+ terminal. i will try to put a delay and see if it works. Thanks.
