SMS send session error at intervals

[bajil2203]

HI, I am using Huawei 8372 wiggle to send out SMS from a node. The SMS send works okay if trigger is not frequent. But with repeated triggers, pops errors as 125003: Unknown or 125002 : Session. To overcome, used a simple queue to hold the messages and triggers one by one with a delay 10 sec, to 1 minute, The pattern is still the same that after every 2 SMS send successful, there will be 2 errors and following triggers send the SMS for the next 2. Followed by 2 error again. The pattern is same that session error pops out every 2 SMS. Any inputs to resolve this or suggest a workaround will be helpful. Please revert. Thanks . The issue looks similar to the other post for reading SMS.

Any tips or a workaround will be helpful. Please advise where this session time can be changed or the current value. Appreciate a reply.

Hmm. This could be that the session time of your router does not match the one I tested with. Current session time it clocked at around 300 seconds . And I did not expose this as a setting in router config.

But that should be very possible. I'll require a bit of time to test it though. In the mean time. Could you find the exact limit of your session?

Also what versions are you running? Node. Js, node-red and this node.

@bajil2203 @zinen I had the same problem when checking for new sms', what I did was mad a new flow where I use the API directly. see here

I have now made a sendSms - you can try that out until node works better.

Untested version but with the session timeout accessible as a config. Please try it and give any feedback.

Install node directly as found on github. This does require you the reach the terminal and can not be done from node-red interface.

npm install https://github.com/zinen/node-red-contrib-huawei-router.git#varible-session-timeout

Thanks for the reply. Will test out and feedback on the test status.

Simulated Offline test looks good after changing the session time. However, couldn't find the timeout in the router configuration, but a random trial of 90 secs for now is good for the flow as now. will test out in the field shortly. Really appreciate the support

Hi, The node is not getting registered in newer npm ver 8.x, but in my PC which is running 6.14.15, is working fine. Please advise. thanks.

Bumped to version 1.2.2a aaf2dd9cca1739fca64d17867139e4b28b852b39 may fix this.

Variable session timeout added to main branch in version 1.3.0.
