Hi all,
Yesterday, I was trying to connect 2 different nano 33 IOT to Arduino Cloud. Helas, no one come into "online" status even after proper config and sketch uploaded.
Then I remember my first purchased nano 33IOT has missing antenna and Sales services had brought me a new one, that I finally broke on the location of the antenna (fat fingers + ambitious soldering project). I so have 2 blind and deaf (concerning Wifi and BLE) boards.
By "chance" I have a third (and perfectly operative) mounted into a project (wireless joypad for my toy car) so I was able to achieve to connect it properly to Arduino Cloud. Issue was clearly the missing/broken antenna on the 2 others boards.
A calm morning today, so I raise my courage and set up my soldering station. I am clearly more a rookie hobbyist than a skilled technician but here boys, what I have finally done:
that is a dirty job, and everything was so small compared to my big fingers! But there, after put apart the first card because one connexion point was metal missing, I took my chance with the second board and a copper wire I cleaned and cut at the good size. Bend It in a "U" and soldered in one point.
When I concluded I was making more bad than good putting more and more soldering (that wiped off immediately), I stopped and tried a simple sketch to make the board connect to my wifi.
Tadam! et voilà, a brand new wifi connecting nano 33IOT (didn't test the bluetooth yet), now connected to Arduino Cloud and bearing my prototype code for a weather station!
Soldering points are clearly as bad for structure and connexion. Surprisingly, wifi works in all my apartment and I just need to test from the outside side of the window to make sure the connexion is ok.
.... till I brreak again the antenna...
