Customer:
I’ve successfully connected my Croduino NOVA board to the internet and retrieved data from a server. Now I need to forward that data to an Arduino UNO board, but I’m unable to achieve this.

vezano uz naš razgovor, imam problema s croduino nova pločicom. uspio sam ju spoiti na internet i dohvatiti podatke s servera. a sad bi htio te podatke koje sam dohvatio na Novu prosljediti na arduino uno pločicu. No to nikako nemogu postiči.
Malo sam u strci s vremenom, pa bi mi brzi odgovor puno značio

Soldered Support:
To communicate between the boards, you need to make a physical connection using RS232 (theoretical range 15m, though practically not recommended beyond approximately 5m depending on conditions).
Connect the following pins:
- Common ground
- Tx to Rx
- Rx to Tx
You can find the pinout for both products on our website.
For communication, use the Serial library with Serial.begin(). The baud rate must be the same on both controllers. Send strings using Serial.println().
On the Arduino UNO (MEGA), read with:
if( Serial.available ) String string_s_nove = Serial.readString();

probati ću ovako na brzinu, ukoliko bude nejasno molim napomenite pa ćemo detaljnije razložiti.
Fizički je potrebno povezati : (RS232 - teoretski 15m, ovisno o uvjetima ne bi bilo dobro ako je udaljenost veća od ccaa 5m)
zajednički gnd
Tx - Rx
Rx - Tx
Pinout možete naći na proizvodima naše stranice.
Za komunikaciju koristite Serial library -Serial.begin(). Bitno da baud bude jednak na oba kontrolera. Stringove šaljite pomoću Serial.println.
Na MEGI čitajte:
if( Serial.available ) String string_s_nove = Serial.readString();
