@prusa-dev If you can, improve/adjust PR to make it compatible with other 3ginfo-lite modem scripts, e.g.

• Protocol names in lower case (ncm..)
• MODE for MODE_NUM 13) MODE="5G NSA |" or MODE="LTE |" or MODE="LTE-A |" to avoid writing with the sign '+' (MODE="LTE-A + 5G |")

@4IceG The modem in 5G NSA mode responds:

As you can see, there is 2 PCC in response. How it should be shown? In current version i did this:

As you can see, there is 2 PCC in response. How it should be shown?

This section Primary band (PCC) | PCI & EARFCN should look a little different (it doesn't show what it should).

We need to take one PCC as primary/main and add the rest to it (then it looks logical).

Now I don't have a PDF open for this modem, so I don't see how they explained it, but it would be good to stick to this form. 5G NSA | B7 (2600 MHz) + B1 (2100 MHz) / n78 (3500 MHz)

Depending on what it looks like in the output of the at command, but to keep PCC + SCC1 / SCC2 and not PCC + SCC1 / PCC + SCC1 + SCC2

[prusa-dev]

This section Primary band (PCC) | PCI & EARFCN should look a little different (it doesn't show what it should).

We need to take one PCC as primary/main and add the rest to it (then it looks logical).

I understand that this section is supposed to show information about the PCC as primary/main, but the modem in 5G NSA mode connects to both 4G and 5G, so the GTCAINFO command response contains two PCC values one for 4G and one for 5G. If Primary band (PCC) | PCI & EARFCN section should only display one value, where should the second value be displayed?

Now I don't have a PDF open for this modem, so I don't see how they explained it, but it would be good to stick to this form. 5G NSA | B7 (2600 MHz) + B1 (2100 MHz) / n78 (3500 MHz)

If I understand you correctly, in 5G NSA mode, do we need to separate the output of 4G and 5G cells in the MODE variable with /?

I've attached AT commands manual. It does not explain why there are two PCC lines in the GTCAINFO response.

[prusa-dev]

Ok, I think I understand I'll make like this https://github.com/4IceG/luci-app-3ginfo-lite/issues/55#issuecomment-1881645327

[prusa-dev]

@4IceG Here is an update.

LTE mode

5G NSA mode

5G SA mode

[4IceG]

Hi @prusa-dev I know I'm complaining, but I would improve LTE-A so that there would not be so many '+' signs. The '+' sign in 3ginfo-lite separates the main/primary band from the aggregation bands.

[prusa-dev]

Hi @4IceG

Could you please write the correct version of what should be in the technology section in the screenshot above?

Right now it looks like this:

Technology: LTE-A | B20 (800 MHz) + B3 (1800 MHz) + B7 (2600 MHz) + B7 (2600 MHz) + B1 (2100 MHz)

Technology: 5G NSA | B3 (1800 MHz) + B1 (2100 MHz) / n79 (4700 MHz)

Technology: 5G SA | n41 (2500 MHz)

[4IceG]

Hi @prusa-dev , Check if the aggregated LTE-A bands are shown ok after my changes.

[4IceG]

I made a small correction removing the last space.

[prusa-dev]

Hi @4IceG Thank you, I'll test it on weekends

[prusa-dev]

Hi @4IceG

I have checked, everything works perfectly.

Here is output:

• LTE-A | B20 (800 MHz) + B3 (1800 MHz) / B7 (2600 MHz) / B7 (2600 MHz) / B1 (2100 MHz)
• 5G NSA | B3 (1800 MHz) + B1 (2100 MHz) / B7 (2600 MHz) / n79 (4700 MHz)
• 5G SA | n41 (2500 MHz)

I made some correction to remove / and + at the end, if band is only one.
