EM 7565 firmware supporting at test commands

IoT Modules MC/EM Series
1

Dear friends,

I am testing EM 7565 modules.
For some reason, I would like to test the capability of modem, such as its selected band/channels/any other command in factory test mode.

In At command guide, There are some command starting with “!da…”, e.g., “!daftmact”, “!dasband”, “!daschan” …

Is there anybody who has the firmware supporting these test commands?
Or Do you know ANY FUTURE PLAN for the commands to be updated?

Thanks in advance!
Kevin

Hi Kevin,

Factory test commands are included in the FW.

at!entercnd=“A710”
OK
at!daftmact
290300

OK

Which one is not working for you?

thanks,
James

Thanks, James!

I can use “at!daftmact” and “at!daftmdeact”, but those are all i can do. ^^

Am I missing some pre-requisites for using other test commands?
Any comment will be appreciated.
(Thanks, James in advance!)

Hi Kevin,

The AT guide has the old/obsolete FTM commands, we are working on an update.
please read the PTS for the correct FTM commands:
https://source.sierrawireless.com/resources/airprime/minicard/75xx/airprime_em7565_product_technical_specification/

read the “Production Testing” section

Thanks!! James!!

Thanks to your comments, I did some FTM test.
but, I still have two question.

  1. Is there anyway to test(check) network information of UMTS, LTE manually.
    e.g.> a. set band and specific channels
    b. find the network information (MCC, MNC, RSSI …)
    in both WCDMA and LTE

     In our application, to find the information of specific neighboring cells are very important.

  2. In FTM test, can I set the receiver frequency as other frequencies not in table?
    I tried to “RF receive path test of UMTS”.
    According to our base station, I put <channel number 10812>.
    But, Error occured.

Thanks in advance.
You really help me out!

Thanks!
Kevin

Hi Kevin,

  1. We don’t have FTM commands to get the NTWK info.

But you can use at!gstatus? in normal mode. At!lteinfo? will list the MCC/MNC

  1. ! DARCONFIG uses uplink (Tx) channel at the center of the corresponding band (rounded down), for both Tx and Rx testing). PTS page 83

So you have to use the UL channel for Tx and Rx testing.

Thanks,

James

Thanks~ James,

  1. I checked and used ‘at!lteinfo’ for lte network.
    But, I can’t find WCDMA network. (‘at!gstatus’ can’t show the mnc/mcc as long as i found.)
    and I think ‘at!lteinfo’ doesn’t show every lte networks in the band configured by ‘at!band’.

I am working for some application in which ALL neighboring network (WCDMA, LTE) information is very important.

  1. UPlink frequency. I will try!

Thanks~ again!

Hi Kevin,

We don’t have AT commands to list the MCC/MNC in WCDMA mode. QMI interface has more NTWK related commands.

“I am working for some application in which ALL neighboring network (WCDMA, LTE) information is very important.”
Are you writing an application to search, list and select available cells/NTWKs?
I’d not do that. The modem is designed to find the best available NTWK.

Thanks,

James
