Sir iam using hl7650 series modem. i have connected hl7650 modem to BeagleBoneBlack device and turn on ppp connection for data transferring purpose. i have ran that device 1 week without interrupting, but suddenly modem is hanging whenever unplug and plug the power after that it working. so what is the problem can u please solve this issue.
Could you let me know how to reproduce this issue? When you say modem hanging, do you mean no any reponse for any AT command? After you see the hanging and reset the modem, could you check result of “AT+EXCEPT” to see if any unexpected reset happens?
