Global Link not connecting to LTE-M

I bought a new Victron Global Link 520. After switching on, the blue LED continues to flash (tested for two days) and status is: Connecting to LTE network. Reception is -73 dB. KPN indicates that coverage in my village is good.

Last Transfer: Never
LTE-M: Connecting to LTE network
Sim status: Ready
LTE-M signal strength: -73 dB
Antenna: External
Operator: NL KPN (20408)

Could there be a problem with the included 1nce sim?

Hi all, we have two batches of GlobalLink 520s of which a certain percentage of units doesn’t work. They can’t connect to internet.

The issue is for GlobalLinks with serial numbers starting with HQ2239 and HQ2242. And then firmware version v2.05. When loaded with version v2.06, all is OK.

What makes this quite a bit more difficult than normally is that it is, using our normal tooling such as VictronConnect, not possible to firmware update a GlobalLink. The only way to firmware update a GlobalLink is via VRM, but then the unit needs to be connected to the internet.

To see if your GlobalLink has this issue:

1) check the serial number

2) check the firmware version. Firmware version is visible in VictronConnect.

And then send it in for an update/replacement.


I’m very sorry for the troubles caused here!


Best regards, Matthijs


Ps. We’re currently checking and where necessary fixing our stock. The only warehouse from which we ever shipped those batches is the one in the Netherlands. Which supplies Europe except for Spain: Spain has its own warehouse.

Note that these fixed units will still have firmware version v2.05; a visual marking will be added to make clear they’ve been fixed.

Hi @mvader (Victron Energy),

I have this situation with a new Globallink 520 from a NW supplier (delivered last week)with serial HQ2239xxxx. Can you identify from this picture of the box it this is the case? I do not see any extra marking indicating that it have been fixed?

I have Global Link 520 S/N HQ2239CAYAH Firmware 2.06 which has connection to the Vodafone LTE network name Vodafone NL (20404). I have added an external LTE antenna at some point resulting in a further improved signal strength. Very often excellent signal -55 dB signal RSSI. However on a daily basis I am facing multiple VRM Notifiers that VRM Database is not receiving data and I see these graph interrupts. I am facing this is issue since the installation Oct 8th 2023. So with and without external antenna.

What Is causing this issue? And how can it be fixed?

Are you absolutely certain that you have LTE-M service in your area? The GL520 will not operate on the normal LTE network.

Screenshot of LTE-M coverage via provider's website. I live in the middle (Terborg). This seems to be enough coverage.

I have been in contact with the company where I bought the Global Connect. Something seems wrong with the Global Connect. They want me to send it back.

I had the same problem. The shop from which I bought (and to which I returned) my GlobalLink 520 says that they have a number of these devices returned with the same problem and that Victron is working on it.

@mvader (Victron Energy) ,

Thanks for the update! The unit I bought and that is back at the shop has a serial number starting HQ2239. It's nice to know that the problem wasn't me!

Sincerely,
Dan.

The replacement unit, with serial number starting HQ2115, arrived today and quickly connected to LTE-M. It is now visible in the web VRM.


Sincerely,

Daniel.

Thanks for the reply. Unfortunately I do not know the serial number because I returned the device to my seller in Almere two weeks ago. This company indicates that they are waiting for a response from Victron. I hope for quick action from Victron.

Hi, for now, all failing units are being asked to be sent back to our office in Almere, and immediately replaced by a new one - from Spain warehouse.


That is where there is good stock at the moment. Shipping might take a fay or two longer.

Earliest by late next week I expect good stock again in NL.

Hi,

Already in february this year I posted a question about my Globallink.
https://community.victronenergy.com/questions/186149/globallink-520-nl-coverage.html

I have connection every now and then but I am unable to have a stable connection. Might this be related to the same problem?
I bought the device in December 2022 @George Kniest. Not sure if it is possible to return the device. For now it is not usable.

Hi,

No, not related.

Sorry to hear it doesn’t work. I’ll check internally how cases are handled and get back to you.
