Getting UNO and sparkfun 4g lte shield to work


#1

Does anyone know how i could get UNO and sparkfun 4g lte shield to work, this is what pops up;

At the heart of the LTE Cat M1/NB-IoT shield is a u-blox SARA-R410M-02B LTE Cat M1/NB-IoT modem.

I have downloaded the sparkfun library and got it registered to the network

here is the shield;

Updating to the latest Blynk library wouldn’t do any harm.

Pete.


#3

Wow some new stuff :grinning: from file>examples>blynk>borads GSM, which one should i use?


#4

like the arduino MKR NB 1500 has the same modem but then the tx/rx pins would be different and i would have to change those somehow. On tiny gsm github it does not state that SARA-R410M-02B is supported.


#5

Or lets put it this way… the reason i am upgrading is because right now im using simcom sim900 and they dissconect all the time. And im wondering if it is not gonna work better with the 4g shield because the rsssi is only around 5 (with simcom) . When i was testing it in front of me it worked really good (the rssi was around 14). So maybe i should add a signal booster. What would your recommendation be? What is the minimum rssi to work stable?


#6

Someone?


#7
  1. I cannot answer. can you provide a link to the manufacturer so i can look it up? Im assuming you already looked there.

  2. Rssi is a value used at layer 1 & 2 of the osi model, im willing to bet you a 12 pack, you arent going to get an answer from layer 3-7 guys on this forum. They will know their app, but not how well its going to work over a bad connection. Im guessing no one has had the same issue or they would probably know.

All that being said, i still would like to see the end result and hope that you can come to a fix.

I did some more testing on the 4g shield and this is how far it goes now…

What do i do in this case?


#10

what would happen if you removed

blynk.begin()

got the client to fullyconnect the generic tinygsm way.
then after you know connectivity is working just fine, you launched

  Blynk.config(auth, server);  
  Blynk.connect();             

#11

What exactly do u mean by “server”. it says ‘server’ was not declared in this scope


#12

I copied this from my old code, and assumed you would modify it to make it work.

yes, please remove the server portion of the code.


#13

now this… no matching function for call to ‘BlynkSIM::config(const char [33])’


#14

When i get stream debugger in the picture…

#15

its having trouble connecting to your provider, you agree?


#16

U could be right but when i run the register operator sketch that comes with the shield library…

Initializing the LTE Shield...
...this may take ~25 seconds if the shield is off.
...it may take ~5 seconds if it just turned on.
LTE Shield connected!

Already connected to: 302 720 Hologram
Press y to connect to a new operator, or any other key to continue.

Connection info:
APN: hologram
IP: 10.59.8.193
Operator: 302 720 Hologram
RSSI: 22


And when i put it in a particle boron 2/G 3/G everything works perfect. so the sim should have data


#17

out of my league…
we were actually out of my league at the start.
sorry man… i better let the pro’s take over


#18

I understand… It would be a blast if Volodymyr Shymanskyy would club in on this or someone who really understands the TinyGsmClientUBLOX.h file
