1.

     Attached is the SLM communication log with new 9160 DK board

    I am using NB card, and 9160 takes about 20 seconds to attach network (please see the log before line 200), i tested this at least for two hours.

    however, after connection, i used AT+CFUN=0 to save current parameter to NVM (please see line 203).

    then, after reset, it takes about 3-5 seconds to attach the network., i also tested this for one hour.

    my question is:

    a. i could't know which parameter is so important that can reduce so much time for 91 to connect to network.

    b. if i could delete my setting like this is default 9160 DK, so i can reproduce this scenario.

2. Another questions why rsrp signal is so good like 64, but 9160 device can't attach to the network, under what conditions, could this happen?

[Hakon]

Hello,

a. i could't know which parameter is so important that can reduce so much time for 91 to connect to network.

The modem stores information about what bands to scan for, that have previously been used, and possibly also other connection parameters that I'm not aware of.

b. if i could delete my setting like this is default 9160 DK, so i can reproduce this scenario.

You can try the %XFACTORYRESET command, and see how that works for you. I don't know if there are other ways to do it.

2. Another questions why rsrp signal is so good like 64, but 9160 device can't attach to the network, under what conditions, could this happen?

I'm not sure what could cause this. Maybe there is no NB coverage, just LTE-M. Have you checked that?

Thanks Hakon,

yes, it is the bandlock that reduce this searching time. confirmed this,thanks again.

and to my understanding, this band would be saved automatically after 48 hours, right? even if i don't send command "at+cfun=0". correct?

for customer product, this device would be powered off after sending data to cloud, so when will those parameters be saved by our modem?

for question 1, if at+cfun=0 is used, and band is locked, if this device is moved and network changes, what would happen? can't attach the network or long time attaching process? what should we do in the code?

for question 2, no there is no CAT-M in china, just NB, let me collect the modem trace, on Monday.

Regards,

William.

Yes. From documentation;

"Permanent mask is stored to Non-volatile Memory (NVM) approximately every 48 hours and when the modem is powered off with the +CFUN=0 command."

William.wei said:

When the modem is powered off as stated above.

It will probably take longer to attach, since the ideal bands for this network most probably are different. You can remove the masks by setting the <operation> parameter to 0 using the same at command.

Then I don't know what it could be. Hopefully the modem trace will show.

[William.wei]

Thanks, Hakon,

for question 1 and 2, customer physically power on the device , after attaching the network and sending data, physically power off the device without sending at+cfun=0; so i asked under such cases, when those bank masks would be saved?

and if those parameters are saved, and devices moved to another places, where the band is changed, maybe devices can't attach the network, right?

i worried that the device may not be able to attach the network again. if band is not correct.

Regards,

William.

If you don't use the XBANDLOCK command, you won't run into this issue even if you set at+cfun=0. The modem will store the last bands that were used, and prioritize those bands when scanning. But you will still be able to attach on different bands. If you use the XBANDLOCK you won't have this luxury. In that case you will need to clear the masks first.
