Hi

Where can I find the latest firmware for my 4G module EC20F, revision: EC20CEFAGR06A10M4G ?

We have more than 2000 EC20 operating in the field. However, lately, two of them stopped operating, with following log message:

It seems pppd failed to receive the dns IP address from the modem. I don’t know what happened to those modules, maybe a firmware update can solve the problem?

Hello FelixC,
我要用中文了
我要储存本机号码
在运行AT$QCPBMPREF=1，之后
可以存储，但是一重启后，就没有了
就又要重新运行
请问升级固件可以解决这一问题吗？

请发送最新的固件给我，感谢
