I have followed your advice and I think this is working, i.e., I am no longer having problems with -9999 values for the CTD.

However, the complex loop code is preventing publication

Hi @aufdenkampe,

I have followed your advice and I think this is working, i.e., I am no longer having problems with -9999 values for the CTD.

However, the complex loop code is preventing publication of data to MMW. I’m sure this is something simple, but I can’t seem to figure it out.

I have tracked the issue to line 483 where the code checks to see if the modem is connected to the internet, i.e., ‘if(modem.connectInternet())’. The lights on the modem don’t seem to power up at all, and the loop just continues reading sensor values and storing it on the SD card. Am I missing something in the setup loop?

Thanks again for your help.

James
