FM350 does not provide dhcp service so IP address needs to be obtained through AT command. When handling fm350, Qmodem will check the IP and update it every 30. |

i see.. another issue ive got is that by default, i couldnt find a way to use AT+CGACT=1,0. I had to use 0 because my isp came preset with an apn in context 0. so i had to manually send the ap commands. but with that, it no longer adds the interface automatically and i think because of that, the ip address is not assigned automatically or at intervals. even though ive configured my apn to be auto, it kept using context 3 cmnet. is there anyway i can use AT+CGACT=1,0 instead? much thanks! |

yes and no. when apn is set to auto choose, it still sets to cbnet. i kinda need it to be empty like "". theres no option for apn to be empty. is there a workaround? its a weird format but it basically has to be exactly CGDCONT: 0,"IPV4V6","","",0,0,0,2,1,1,,0,1,0 |

When the dial script reads the configuration, both the empty value and auto will be set to auto. There are many Chinese users in this project. Chinese users will not be available when setting apn to auto when using fm350. It needs to be set to cbnet, which will cause the problem you encounter. However, the dial script setting pdpcontext does not support too complicated settings. Based on your needs, it is recommended that you modify Find the case corresponding to fm350 (fibocom/mtk) in the at_dial function, and replace the dialing command with your special command. |

You can navigate to Modem Settings > Modem List > FM350 > Edit , then set the pdp context index to the value you need.

I have got a FM350GL using RNDIS over USB. I would have to run at+cgpaddr=0 to find out the ISP assigned IP address and manually use this static address for my WAN interface. It becomes annoying when the IP lease ends and I have to do the process again. Is there anyway I can let WAN use DHCP and obtain that address automatically? Does Qmodem automatically manage this for me?
