Question

As far as I know the commands are:

• uci set [email protected][0].band='manual'
• uci set [email protected][0].lte='lte_b20'
• uci set [email protected][0].umts='wcdma_900'
• uci commit simcard
• /etc/init.d/simcard restart
• reboot

But after the reboot the modem still sticks to b1 instead of b20 (or 3g if b20 would not be available)

If I do the change via the web interface than it works and the output looks like: [email protected]:~# uci show simcard

• [email protected][0]=sim
• [email protected][0].modem='3-1'
• [email protected][0].position='1'
• [email protected][0].primary='1'
• [email protected][0].pincode='1234'
• [email protected][0].auto_apn='0'
• [email protected][0].enable_sms_limit='0'
• [email protected][0].service='auto'
• [email protected][0].band='manual'
• [email protected][0].umts='wcdma_900' 'wcdma_2100'
• [email protected][0].lte='lte_b1' 'lte_b28' 'lte_b38' 'lte_b41'
• [email protected][1]=sim
• [email protected][1].modem='3-1'
• [email protected][1].position='2'
• [email protected][1].auto_apn='1'

My manual config looks like: [email protected]:~# uci show simcard

• [email protected][0]=sim
• [email protected][0].modem='3-1'
• [email protected][0].position='1'
• [email protected][0].primary='1'
• [email protected][0].pincode='4798'
• [email protected][0].auto_apn='0'
• [email protected][0].enable_sms_limit='0'
• [email protected][0].band='manual'
• [email protected][0].umts='wcdma_900' 'wcdma_2100'
• [email protected][0].service='auto'
• [email protected][0].lte='lte_b20'
• [email protected][1]=sim
• [email protected][1].modem='3-1'
• [email protected][1].position='2'
• [email protected][1].auto_apn='1'

Hello,

You are using uci call not correct.

First you need to set like list not option bands. That's why you commands not working. Here is solution:

• uci set [email protected][0].band='manual'
• uci delete [email protected][0].lte
• uci add_list [email protected][0].lte='lte_b20'
• uci delete [email protected][0].umts
• uci add_list [email protected][0].umts='wcdma_900'
• uci commit simcard
• /etc/init.d/simcard restart - (you don't need this command)
• reboot - (You don't need to restart all router to get applied changes. You could restart only module with `mctl -r` command or just re-init modem AT commands by using `ubus call gsmd reinit_modems` command.)

Many thx, this works perfect via CLI. 

Next step is to get it working via SMS. Working is:

• uci set [email protected][0].band=manual (or auto)
• uci commit simcard

Not working is:

• uci delete [email protected][0].lte
• uci add_list [email protected][0].lte='lte_b20'
• uci delete [email protected][0].umts
• uci add_list [email protected][0].umts='wcdma_900'

SMS not accepted is:

• `mctl -r` or
• `ubus call gsmd reinit_modems` 

What do I have to change to get it working, Why do I use SMS?, because than I can reach the modem if LTE is down.

Hello,

Yes, this is shell commands and SMS-utils don't execute shell directly.

I suggest to create a 2 different profiles and switch them between if needed.

I think that SMS-utilities doesn't have anything to restart modem directly, so best options at this moment is restart device with SMS-utilities restart command.

Goodmorning,

Is it an option to generate a CLI link via the RMS API (/devices​/{id}​/connect​/cli) and then perform these actions?
