why mysensors is based on nrf24?

[Reza]

@chbla
do you use RFM69? this is work better than nrf? about distance and wall
RFM support repeater feature? and we can choose different channel ?

[chbla]

I'm using RFM69 yes, and it has no problems.
I don't need repeaters at the moment, as far as I know it's software based?

[Anticimex]

@chbla you are correct. The radio is fully supported and the repeater feature is a library feature, not a radio feature. It is a feature of the MySensors protocol.

[Reza]

thank you friends for answer.
about channel? MY_RF24_CHANNEL
can we use several channel with RFM ?
generally RFM work better than NRF ?

[Anticimex]

@Reza how about you read MyConfig.h?

[chbla]

@Reza it depends on the use case I think, peope are using both, both are working. NRF24 is easier to set up and seems to have more support. Just try it :)

[Reza]

for help to my friends that use NRF. i test several model. but most are not really range.this model was best of NRF. with this model i have connect with 60cm wall and 10meter distance.
if you want have a good connection, so use this model:

but i think NRF is not worthy mysensors and efforts of mysensors team :pray:

i am weak in english sorry i know repeater feature is in mysensors library, but i think about channel i think this is just for nrf. is that right ?

@chbla i am very happy with mysensors. i have very sensors and relay and every day i am try to build a new sensor and a new devices :) if there was a stronge and good and easy connection so this was very more intresting

I think you have missed a couple of details @Reza

When mysensors started out, the cheapest / best approach was to use the nRF24L01, rfm69hw was not available. So the project evolved around this radio. The RFM69 came in at a later time.

Unfortunately a lot of Chinese saw easy money, with counterfeit chips, and started to create less than optimal fake versions. That will probably also happen to rfm69hw (and are probably already there).

So we keep nrf, as it is there in the core.. It's up to you and other hackers, to decide what you want to use

hey dear friend,

be like water ;)

[Anticimex]

@Reza If you read MySensors.h you will find what configuration possibilities the various radios have. Try looking for information instead of just begging for it all the time.

[Reza]

@tbowmo
oh thank you for explain :pray: and thank you all mysensors team. really thank you. mysensors is intresting really. i try to found best and easy and without any trouble of solution for connection . we are easy to build all sensors and relay(with mysensors library) so this is intresting more to easy , very easy connection between rooms... :)
again thank you all mysensors team and hero members :pray:

@Reza so, topic closed?

[Reza]

@Anticimex dear friend , i am trying for learn and work well with mysensors library , arduino and radios...
believe me i trying every days. now for 1.5 years. i am trying every days. but some time i dont know where found my problem and my question. i start learn arduino with mysensors library. because i am Interested very very. now i can write each sketch for sensors and relay. this is for your help .thank you

[Anticimex]

@Reza have a look in the file. It's designed to offer clear understanding of the various configuration options. And gives you a good overview of what settings you can place in your sketch to configure the library to your needs (what radio to use, what channel, transmit/receive power, pin assignments, etc.)

hi. yes thank you. i see forum and site every days and read new topics and Newest Articles and Recently Updated :)
i hope mysensors development every days in all of world , and the team be healthy always.
thank you

thank you dear friend . i will see and read and translate .thank you

And do not forgot about law restrictions in some countries, EU and etc.
For example with 868 Mhz your device can transmitting max 1% of time per one hour.
Maybe problem for gateway node?
2,4 GHZ is relatively free all over the world.

@kimot this is true . but also about 2.4 Ghz i think there is better modules.what module is using in raspberry pi 3 ( without antenna) or wifi router or milight modem or etc ... !? These are 2.4 Ghz . But working for more distance without any problem . i dont test esp8266 (12-12E and very new models) but Don`t you think this is work better ? I didnot work with any radio. Just nrf and a sender with receiver 433 .

[Reza]

Now for a wifi gateway mysensor used NodeMCU with a esp8266. Then connect a Nrf to NodeMCU . sensor network is with nrf and connection between router and gateway is with esp8266. If esp8266 work good , can we use esp8266 module for each node ? I did not work with esp and this is just a idea
