I have recently installed a GlobalLink 520 on my boat in the UK. LTE-M provider is Telefonica Europe, which is O2 in the UK.
It’s connected to a BMV712S and a SmartSolar 150|45. Everything works fine. I have a really good signal (-65dBm reported) utilising an external antenna.
However….. whilst most of the time the whole system works perfectly, some days I experience large time gaps in the transmission of information. Instead of 15 minutes, there can be a gap of 2, or even 3 hours. This can happen several times a day, on some days. I’m convinced it’s not my antenna setup as the GlobalLink reports a very strong signal.
Any ideas what is causing this, and is anyone else experiencing the same phenomenon? Any solutions? Or is it a polling problem with Telefonica Europe?
PS: For the avoidance of doubt, my boat has been continuously moored, in the same place, since the GlobalLink was first installed about 10 days ago. ie: no movement is involved.
