RF Nano = Nano + NRF24, for just $3,50 on Aliexpress

[torfinn]

Hi ! Got a couple of these. Hard to say if its + chip ( but I guess not ). Anyway I am not able to get them running a simple test sketch. Only get RBR:REG=23, VAL=17

@torfinn
i had to set
#define MY_RF24_CE_PIN 10
#define MY_RF24_CS_PIN 9
on mine (definetly not + btw) a while back....

I just got my order of 3, this time I got the nRF24L01+ version.

:-D Now I wish I hadn't bought 70 of the old version already.

They're working well though, very happy with them. Great for workshops.

[torfinn]

@zen85 Thanks I got it to work but if I add #define MY_DEBUG_VERBOSE_RF24 i still get RBR:REG=23, VAL=17 filling the console....

@torfinn These settings should make it work, regardless of which version you buy:

// If you are using an RF-Nano, you have to switch CE and CS pins.
#define MY_RF24_CS_PIN 9                            // Used by the MySensors library.
#define MY_RF24_CE_PIN 10                           // Used by the MySensors library.

// Enable and select radio type attached
#define MY_RADIO_RF24
#define MY_RF24_PA_LEVEL RF24_PA_MAX

// Mysensors advanced settings
#define MY_RF24_DATARATE RF24_1MBPS                 // This datarate is supported by pretty much all NRF24 radios, including the RF-Nano.

Hi guys
just a newbie in MySensors, i am buikding my home net with RF24 radio.
Just received 4 of this rf-nano (+ chip) and set one into relay device
With my Wemos D1mini pro + NRF24L01 +PA+LA gateway, it works in my whole (relatively large) house (approx 30m through a lot of walls and armed floor).
Really handy for small boxes projects, the missing functionality is the interrupt pin not (easily ?) accessible for battery powering

[Sherco49]

I continue my test with this chip, and solved an issue in declaring children of a node

I tried the relay actuator with 2 relays, the second one never wanted to get an ACK message for the presentation message
I tried with 3 children relays , first is ACK, second still NACK and 3rd .... ACK again !

Even if it was not my first thought, i finally insert a wait(1000) between each present line which solved the problem

hope it can help

You might be interested by the board I've designed. Not "RF Nano" but "RF Pro Mini". Of course you need a "USB to serial" programmer but it directly runs on batteries.
See here and here.

[martim]

@echi Where could you order this board?

[TheoL]

@martim Just search for RF Nano on Aliexpress. Haven't looked for the cheapest one, just the first that says LRF24L01+. Although not certain if it is really a + version of the NRF24L01.

This is one on Aliexpress

[ncollins]

@martim I think this is a better alternative: https://www.electrodragon.com/product/nrf24duino-arduino-mini-plus-nrf24l01-board/

[TheoL]

@ncollins That is a nice board indeed. I haven't checked because I will order some things after dinner. For me it is a must to keep the arduino Nano footprint. So I can replace the nano and nrf in some of the projects I already built.

[martim]

@TheoL I meant the board of @echi here as I need battery power board and this seems to be working well.

[martim]

@ncollins If this board is suitable for battery use? I don't see how much current it uses.

[ncollins]

@martim Yep, you just need to make sure to turn off the EEPROM module after setup, then it's basically an Atmega328p and NRF24L01+. It has solderable jumpers to bypass the voltage regulator and status LED.

Here is a claim of 12uA in sleep: https://forum.mysensors.org/post/96631

[TheoL]

Why not go for a sensebender? https://www.itead.cc/mysensors-micro.html

I have one in each room, measuring temp and humidity. It works great

[martim]

@TheoL way to expensive.

[martim]

@ncollins okay, give it a try.
