Re: Sparqee Modem Hang

Hi, We have this pattern. We are sending normal SMS for quite number of times successfully. Then the modem will fail sending. So if we keep on sending AT command, the modem will hang indefinitely where all software reset is not even possible. Is this a firmware issue? Can we update the firmware of Z...

Re: Sparqee Modem Hang

Hi, I cannot even do a AT during minicom. It would just refuse any input and naturally there will not be any return result. I have tried power down but it does not response at all.

Sparqee Modem Hang

Hi, I am having a sparqee cell with shield running raspberry pi 3+. After sending sms by pdu for a while, the modem hangs. When I minicom in, no AT command can be accepted. Even after running the turn on script does not help. We have to manually switch off the power and on back so that the modem can...

SIM Reader

Hi,

Currently, the SIM Chip Reader is located underneath the chip of cellv1.0.

This is very inconvenient for removal/change of SIM Chip.

Do you have another version that face outside for easy removal of SIM Chip? Or SIM Chip reader extension or some sort?

Working with existing raspberry OS

Hi, I have just got the shield and cell on my raspberry pi 3 model b with jessie OS. Since my rasp OS is already installed with my program, I would not want to reformat with the steps you describe. I setup the unit with 5 green LED and 1 red LED. This means the CELLv1.0 is unregistered with a cellul...
