How does ep06e control 2ca? Polymerization doesn't work

1+1 AT+QCFG=“band”,0,2
3+3 AT+QCFG=“band”,0,8

AT+QNWINFO

+QNWINFO: “FDD LTE”,“46011”,“LTE BAND 1”,100

OK

AT+QCAINFO

OK

CA aggregation information not found

Can you reset the band info to automatic to see if it works

What country are you? It seems that the module is not suitable for CA aggregation here. EP06 does not support 1 + 3 special code. 1 + 1 + 3 + 3 combination has no effect. Is the device automatic aggregation?

The test module supports 1 + 3 combination
Enter the following at command

AT+QCFG=“nwscanmode”,3,1
AT+QNWLOCK=“common/4g”,1,100,53

Aggregation CA is displayed but not stable. I need the combination of 1 + 1 and 3 + 3. When I lock 4G mode, aggregation is automatic, and the module cannot lock the frequency band I need

中国大陆CAT6的网络好像不怎么样。我们在大陆只用CAT4.

CAT6 is not working good in China.
