Error message - normal or some problem inside qmicli in parallel usage?

[Martin Maurer]

Hello,

I am using two modules (Quectel 4G and 5G, both time Telekom prepaid SIM 
card) at the same time on a Raspberry PI 4.

I am controlling both at the same time from different ssh session.

Today I got multiple times:

error: couldn't create client for the 'dms' service: CID allocation 
failed in the CTL client: Service mismatch (requested 'dms', got 'wds')

I am using the following commands:

(for one of the modules)

sudo qmicli --device=/dev/cdc-wdm0 --device-open-proxy 
--dms-get-manufacturer
sudo qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-model
sudo qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-revision
sudo qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-ids
sudo qmicli --device=/dev/cdc-wdm0 --device-open-proxy --uim-get-card-status

as well as connection establishment like

sudo qmicli --device=/dev/cdc-wdm0 --device-open-proxy 
--wds-start-network="ip-type=4,apn=internet.telekom" --client-no-release-cid

and parallel

(for the other of the modules)

sudo qmicli --device=/dev/cdc-wdm1 --device-open-proxy 
--dms-get-manufacturer
sudo qmicli --device=/dev/cdc-wdm1 --device-open-proxy --dms-get-model
sudo qmicli --device=/dev/cdc-wdm1 --device-open-proxy --dms-get-revision
sudo qmicli --device=/dev/cdc-wdm1 --device-open-proxy --dms-get-ids
sudo qmicli --device=/dev/cdc-wdm1 --device-open-proxy --uim-get-card-status

as well as connection establishment like

sudo qmicli --device=/dev/cdc-wdm1 --device-open-proxy 
--wds-start-network="ip-type=4,apn=internet.telekom" --client-no-release-cid

I assume some actions querying infos collide with collection establishment?

Is there some log I can provide/analyse in case I see such an error?

Best regards,

Martin
