Hello to you all,
Firstly, I am completely new to cell phone technology - indeed my wife says I am living in the stone age - but a quick learner and have spent decades doing IT support, albeit older systems.
Secondly, I was quite impressed when our suppliers mentioned they use MikroTik products as a quick web search showed they seemed to be in a different league compared with the usual domestic routers. We are quite rural (in South Wales - so not as rural as some members!) and landline broadband is a bit of a joke. Therefore we are using an SXT antenna with built-in modem to converse with a Hap AC Lite. RouterOS is v6.47.9.
Thirdly, I am impressed with the detail of many of the topics on this forum and the expertise of the members. Although 4G LTE is new to me I was quite surprised to see that the old format of modem commands are used. I used to program them decades ago!
On first installation the system did report a SIM error but came up ok and we were very pleased with the speeds. After a day though the LTE1 interface stayed very dead and we ordered and received a replacement SIM. (I cannot understand what a fiddly job that is up a high ladder! All that engineering and they have a design where the sim automatically falls from your finger into the base of the unit!)
It stayed up and running yesterday evening and we had a “buffering-free” session on the TV for the first time ever. This morning there was no internet access at all and LTE1 was not running. I added LTE logging and increased the memory logging lines to 5000. Disabling and re-enabling the interface did not help. I powered off the antenna and it still did not come back up but then suddenly sprung into life.
I then noticed a few dropouts and one log I captured had this sequence:
15:45:33 lte,async lte1: sent AT+CPIN?
15:45:33 lte,async lte1: rcvd +CME ERROR: SIM failure
15:45:34 lte,async,event lte1: *SIMDETEC:1,SIM
15:45:34 lte,async,event lte1: *ICCID: 8944303603049920075
It has dropped 24 times in about 4 hours so I am wondering how often it has to interrogate the sim.
I do not think that the second SIM is also faulty.
Any help would be gratefully received!
Gerald.
PS I was pleased to see that RouterOS will support MQTT client interface. I use that with Home Assistant to monitor a few things including a ground source heat pump so will attempt to monitor the modem and router.
