Customer:
I have two Dasduino Core boards and two Dasduino Connect boards, an NRF24L01 adapter for Dasduino, and 2.4GHz NRF24L01+ transceivers with amplifiers and antennas. I want to use this equipment to transmit wireless data (for example temperature) using NRF technology at distances of 200 to 300 meters without obstacles between transmitter and receiver. I plan to use one board for transmitting data and another for receiving data and displaying it in Arduino IDE’s Serial Monitor. However, I don’t know how to connect the pins of these components. Can I use the example .ino programs included with the NRF24L01 adapter library for my application? I’m also wondering if I can use either Core or Connect board for this project.

posjedujem po dva komada Dasduino Core i Dasduino Connect pločica, NRF24L01 adapter za Dasduino pločice i 2.4GHz NRF24L01+ odašiljač i prijemnik s pojačalom i antenom.
Pomoću navedene opreme planiram realizirati bežično slanje podataka (npr. temperature) NRF tehnologijom na udaljenosti od 200 do 300 metara (bez prepreka između odašiljača i prijemnika).
Htio bih iskoristiti jednu pločicu za odašiljanje podataka, a drugu za primanje podataka i ispis u Serial Monitoru Arduino IDE-a.
Međutim, ne znam kako povezati pinove navedenih komponenata i mogu li za svoju primjenu iskoristiti primjere .ino programa koje ste priložili uz biblioteku NRF24L01 adaptera.
Zanima me i mogu li iskoristiti bilo koju (Core ili Connect) pločicu u ovom projektu.
Vaša pomoć bi mi puno pomogla u ostvarivanju ovog vannastavnog studentskog projekta.

Soldered Support:
The connection is done via SPI communication. You can easily find which pins on Dasduino are used for SPI and connect them accordingly. Dasduino Core is very similar to Arduino Nano (with some improvements and enhancements) so any tutorial on the internet applies to Dasduino as well. If you have a Dasduino Core with female headers, you can plug the adapter directly into it as a shield. It should also work on Connect. It is similar to NodeMCU or Wemos which use ESP8266, and anything you find online for those boards applies to Dasduino as well. You connect the receiver and transmitter sides to the same pins because these are transceivers and can both send and receive.

Najjednostavije je ovako nešto, dosta jednostaviji kod za prijemnik i odasiljač. Povezuje se putem SPI komunikacije, možete jednostavno pronaći koji su pinovi na Dasduino za to i povezati. Dasduino Core je jako sličan Arduino Nano-u (uz neka poboljšanja i unaprijeđenja) tako da svaki tutorijal na internetu vrijedi i za Dasduino. Ako imate Dasduino Core sa ženskim headerima, onda taj adapter samo uštekate u njega, kao shield. Trebalo bi raditi i na Connect-u. On je sličan NodeMCU ili Wemosu koji ima ESP8266 te također sve na internetu za te pločice vrijedi i za Dasduino. Spajate na iste pinove i prijemnu stranu i odašiljačku jer su to primporedajnici te mogu i slati i primati.

I’m making progress with the adapter and things are much clearer now. I have another question about connecting the NRF24L01+ with amplifier and antenna to the board. It has 8 headers close together and the wiring is a bit difficult.

hvala Vam na odgovoru, napredujem sa adapterom i stvari su puno jasnije.
Još bih Vas pitao imate li savjet u vezi spajanja NRF24L01+
s pojačalom i antenom sa pločicom ?
On ima 8 headera jedan blizu drugoga pa je spajanje malo teže.
Soldered Support:
Why would it be more difficult? It has the same pins as the NRF24 module without antenna - you can use the adapter the same way. If you connect without the adapter, try using the shortest wires possible because SPI communication doesn’t tolerate long wires. Long wires can cause interference and the whole thing may not work properly.

Kako mislite da je teže? On ima isto pinova kao i NRF24 modul bez antene, isto ga možete preko adaptera.
Ako spajate bez adaptera, pokušajte koristiti što kraće žice jer SPI komunikacija “ne voli” pre duge, mogu postojati smetnje i da na kraju cijela stvar ne funkcionira kako treba.
