how often do these drops occur? steve should not cause any connection drops. are you sure that steve's network is stable? are you sure that charging stations maintain a stable network connectivity? can you post any logs for more context?
Yes, I think we need machine to machine SIM

i don't know how to start any investigation with this bit of information.
i assume that your problem is not because of steve, but other components. i cannot help you there.
Hi
I switched to machine2machine SIM but I am still seeing dropping off of one of the chargers. Will you be willing to look at the log and help me figure out why the charger is dropping?

... can you post any logs for more context?
sure, i was willing one week ago, i am willing now :)
THanks for helping! I really appreciate it.
here is my report:
sessionId=bee9343d-6ca2-1b7a-5733-14ab885151b0
). in another case, the connection was open for almost 6 hours (sessionId=2c30dcca-dee2-f49d-148a-cc4130a00485
) without issues and then suddenly it was being dropped.the logs of steve do not tell anything further. there is no indication that steve is at fault. if you want to continue your investigation and find the root cause, you should look at the logs of the charging station. hopefully you can find the reasons there.
my strong assumption is that the instability of wireless networks can cause connections being dropped and reopened from time to time. 14 connection drops while 846 messages were exchanged within 16,5 hours can be considered acceptable. the missing patterns in connection drop behavior support my assumption.
Hi
Thank you so much for your help. I will investigate further on the machine side to see why this could have happened.

here is my report:
- the logs cover the operation of approx. 16 hours and 30 mins
- during this period 423 messages were sent successfully
- 14 "abnormal connection close" cases
- the error codes are 1006 and 1011
- there is no pattern to why these connections drop. in one case, the dropped connection was open for a couple of milliseconds ( sessionId=bee9343d-6ca2-1b7a-5733-14ab885151b0). in another case, the connection was open for almost 6 hours ( sessionId=2c30dcca-dee2-f49d-148a-cc4130a00485) without issues and then suddenly it was being dropped.
- most of the drops were during the night (from 00:00 to 08:00). after 8:00 there are only 3 cases. however, i dont know that to do with this info.
