I have received my 3G shield few days ago then I tried to send SMS, it works fine but when I tried to test take picture sample I have no response at the stepAT+CCAMS
The program still wait for "OK
" response but nothing happens,
but by adding some verbose logs by testing response on serial line I have sometime these type of strings:VIEAL NTSAE ÿÿÿÿÿÿÿÿÿÿÿÿÿTCASÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ
and other time a more explicit message as CAMERA NO SENSOR
despite the camera is well connected,
Notice that at beginning I have supplied my card with USB and after by an external supply of 18V, I hope that the card and the shield support this voltage ....
If someone could give me a beginning of explanation
