I found out that i need the newest firmware on my shield.
i’ve already recieved the tools to do it.
The boards i own are:
- Arduino Uno
- Arduino Leonardo
The question is, is it possible to update with one of those boards?
or do i need a Arduino ZERO or Serial USB or something like that?
You should be able to do this with an Arduino Leonardo.
Open the example sketch from the Arduino IDE.
File -> Examples -> Sodaq_nbIOT -> nbIOT_serial_passthrough
I’ve uploaded the sketch and he won’t update the firmware.
The image i get:
After some seconds i get the message: “timed out trying to establish connection”.
It’s the same result as when i tried to update with the GND to RSR with a cable.
What can i do?
Thanks in forhand,
Yes i did… i put the cable in the GND and keep the cable on that point.
Then i pushed update…
How i setup my device for setup:
- The shield is put on a Arduino Leonardo with code:
- I bought a Serial to TTL device to connect with the SARA-N211.
- I recieved the UEUpdater with firmware from JAN.
- I connect the Serial RX to RX, TX to TX, GND to the RST Pin from the SARA-N211 shield.
- Open the UEUpdater, Select com port from my Serial to TTL
- Choose my firmware
- Press update.
it just won’t update?
I thought maybe wrong labeling… so i tried to change the RX and TX, still no result.
What am i doing wrong?
Somehow the update worked…
my Serial to TTL needed to be on 3.3V instead of 5V.
Also i kept the reset pin to long on the reset.
The next problem is, the connection with All Things Talk still won’t work out of the box…
Therefore i use the example from the library nbIOT, example: “nbIOT_Humidity_Temperature_AllthingsTalk”.
Firmware version: 06.57, A07.03
When i use the Serial_passthrough sketch to talk to Ublox, i’m checking if i can get a connection.
Every AT-command works just fine till i use the command: AT+CFUN=1, i’ll get an error.
That will explain why the sketch to all things talk won’t work.
What can i do to put my antenne back on?
