Hello all,
I have had trouble with getting BlynkTimer to work correctly,
I was getting the error…
> Compilation error: 'BlynkTimer' does not name a type; did you mean 'BlynkBitSet'?
I followed some online instructions and deleted and reinstalled the library to the latest version, although I have never installed the library before so I believe it just installed the same version again.
Once I reinstalled the library, this didn’t resolve the BlynkTimer issue, but now there is a new issue where the device won’t connect, I just get this in the serial monitor over and over.

You need to move these libraries to the top of the sketch above the Blynktimer line.
and these lines need to be the first lines in your sketch
#define BLYNK_TEMPLATE_ID “TMPL2GriGYWFd”
#define BLYNK_TEMPLATE_NAME “Spira Fairy Lights Only”
#define BLYNK_AUTH_TOKEN “xnPhxFufNr8z5yRC7ebn7RGB7Rvz5uvr”

Without seeing the serial output that appears when you first boot the board its difficult to say, but it looks like a GPRS connectivity issue to me.
I don’t understand why you have WiFi credential in your sketch when you’re connecting via GPRS…
Have you successfully connected to a mobile network using the SIM card you have installed in your board?
Pete.
Hello Bill,
Thank you so much for this, so obvious now that you say this, of course the library needs to be included first!
Best,
M
Hi @PeteKnight,
I started with an example sketch I found online, I am guessing that these were present and I haven’t removed them, I couldn’t find an example sketch for the Arduino MKR 1500 NB in the example browser.
Can I safely remove these, anything else I need to do?
Best,
M
Yes.
Taking onboard my comments about serial monitor output would be a start.
Pete.
Hi @PeteKnight,
The board is now connecting properly, with the occasional disconnect and reconnect after following the advice of @Bill_Donnelly.
This is a pretty standard start up output, ping does vary a little.

Hello @Bill_Donnelly @PeteKnight,
My connection issues have reared their ugly heads again.
I am not able to connect to the cloud, I have tried existing code that I know that works (and is on deployed devices that are working).
I have stripped it right back to this code.

and this is what I get from the serial monitor… The occasional ‘Cannot init’ then repeated failed attempts to connect.

I don’t really know where to go from here, have tried multiple MKR 1500 NB devices.

I keep saying that it’s the serial output that appears WHEN YOU FIRST BOOT YOUR BOARD that tells us the most, but despite me saying this you haven’t posted this so far.
Also, you should be posting the text from your serial monitor, not a screenshot.
Pete.
Hi @PeteKnight,
This is everything that the board sent to the serial monitor, I am guessing something is being missed as the computer is not ready when the board is sending it’s bootup messages, I will try to use Putty or some other method to capture it.
I just copied the text from the serial monitor into <>, I don’t know why it has formatted it like that.
Best,
M
@PeteKnight,
So weird, I reconnected the device to try and capture the startup messages, and the device connected straight away to Blynk, was there issues with Blynk yesterday?
I had to enter a delay(1000); at the beginning of void setup() to capture this but here it is.

Any idea of what might have been going on?

These two messages seem rather odd!
This ping time is very bad. Long pings on GPRS are normally caused by poor signal strength. What sort of antenna do you have connected to your GPRS modem?
Are you in an area of poor cell tower coverage for the mobile provider that you’ve chosen for your data SIM?
Pete.
Hello @PeteKnight,
I have connected a larger antenna than the one that comes with the MKR 1500 NB and I get this.

A little better but not great,
I am in an OK area for coverage, but indoors it is not great here, thick walls etc.
Our devices will be installed all over the country, but always outdoors in plastic enclosures.
I had a message from Dimitry about changing over to the Singapore server but nothing came of that, I will chase that up.
I think the double messages were because when I added the delay(1000); the device would no longer connect, so I removed it and rebooted the board, hence the two messages.
Best,
Matt
