With the limited information you have supplied it is almost impossible to say what your problem is. We need more information, such as:- What are the LED indications for the CM module? What AS blocks are you using in your program to interface to the CM module? Are there any status / error codes from these functions?

pavans Posts: 81 Rating: (0)	Hello Smiffy , Thank you for your support, Please find the attachment for my Project. In Main2_OB1, I have used while loop but the program is not repeating tough the condition is satisfied. Please help me. And also if you dont mind can you suggest me how I can take the values in array r[3..10] of data block seperately into a variable & convert them in to a single decimal number because they will be recorded in HEX. Thank you very much, Have a nice day, pavan Attachment Solar.zip (555 Downloads)
