Camera issue with GM862 PCS

Wireless & IoT
1

I recently got an eval kit.

I am able to access the device and send AT commands to it…i have one solid red LED and a blinking red status LED. I currently have no sim in the device, because I do not have one yet.

I am just trying to turn on the camera, capture an image, and send it via serial port. Here is what i get:

AT#CAMON

OK

AT#TPHOTO

ERROR

AT#TPHOTO

ERROR

AT#CAMOFF

ERROR

ERROR

AT#CAMON

OK

AT#TPHOTO

ERROR

AT#RPHOTO

ERROR

I have the camera attached to the device, with the exposed leds on the ribbon facing the OEM module.

Any suggestions on what I can do to get this working?

Give an AT+CMEE=2 command first, so that you get meaningful error messages rather than just “ERROR”. I suspect the problem will be obvious then.

AT+CMEE=2

OK

AT#CAMON

OK

AT#TPHOTO

+CME ERROR: Camera Initialization Error

AT#RPHOTO

+CME ERROR: Camera not Found

Wow, thats quite obvious. But the question is, what do i do next?

This picture is a little blury, but you can get an idea of the connector orientation…

Huh, I would have guessed “no SIM inserted” as the detailed error message - the GM862 has lots of commands that require a SIM for no apparent reason.

I don’t have the camera module myself, but it looks like you have it connected the right way around. Is the sliding portion of the camera connector snapped back down firmly?

I just found an old deactivated SIM that shows up as good (CPIN READY), i am getting CREG 0,2 … so I would suspect that its happy enough to take such commands.

I also have checked all the connections, and everything seems snug.

Still, no luck on the camera. I get the same “no camera present” error messages.

Hmm. The camera orientation is correct and you shouldn’t need a sim to snap a photo (sending it via email you will).

We may have to do a return to see what the problem is. Email jeff @ sparkfun.com with your order # to get a new board sent to you.

What was the resolution for this issue? I have a module / camera with identical issues that we recently received from SparkFun.

In addition I am unable to control the GPIO interface (w/ camera unplugged) via the at#gpio= command. To be sure what I attempted is “at#gpio=7,1,1” to set GPIO7 high. It isn’t clear if the pin was driven low or just undriven, but the result wasn’t a high output on GPIO7.

Hi,

All the EVK v2 boards are tested with camera so the camera should be fully operational. More than likely there is a solder connection problem between the 50-pin molex connector and the PCB. Take a look. If there’s a problem, we’d be more than happy to take a look at it.
