I am using mangOH Green board with WP7502 chip now.
Two weeks ago, after I followed the quick start manual, everything works fine. But when I tried to use it today, after I enter “cm data connect &” command, although the board can ping to website, Windows10 system cannot connect through mobile network connection, it always report the error: “Can’t connect to this network Enter an APN & try again”.
After several hours fixing, I still have no idea what is wrong, so I reset everything: reinstall the mango board windows driver, reset the mango board, reinstall putty and reset all windows network settings. However, the new problem comes: I can connect to the mango green board and get information if I type “cm data” “cm radio” or some other commands, but if I run “cm data connect &”, putty would say: “software caused connection abort”. I tried many solutions for putty, but none is working.
Can anyone help me with the problems or give me some suggestions?
PS: I found that even if I try to unlock the SIM with “cm sim enterpin” command, ssh crashes. As I tried on both linux and windows systems, they behave the same, I guess there is something wrong with the board or configuration.
Thank you very much!
