Programming RFM radio modules in Basic

[Denner]

Hello,

Someone has code-tested the RFM69 module.

THX.

[astanapane]

Im trying to figure out for most of the threads why RFM69s and LORA RFM 9x are so difficult to handle.

Technology goes to plug and play modules, and those shouldnt be an exception. You should use them in order to help you, and not make you feel like you need to know rocket science to program those little modules.

Richard gave me some directions, in an other similar thread, but i cannot accept that we need to right 2 pages asm code or an other higher level language in order to send a HELLO from one end to the other.

At the end of the day, i understand that those modules will not sell, or someone that would like to share the fixed library for PIC BASIC Pro, and just let all the other to use the modules in the most easy way, like all the arduino users do.

Anyway, i'm not a professional, just doing this as a hobby.

I cannot understand why the people that really know how to program and handle typical application, are not sharing their knowledge. In nowadays all things are plug and play. That should be the way we all think and help.

I'm a Chief Design engineer well known worldwide, in 3D printing Congenital Heart Defects for surgical planning, and i have shared for free my knowledge to 150 universities and hospitals in EMEA region. I dont want to make money of it. I want to be known and my name to be remembered in the future.

I know in the other hand that there are people come in here, ask for a code, and then they presented like it is theirs and they also make money out of it. So what? Those people will never do something good in their lives. I do share my knowledge and i have in mind that 10 out of the 100 people in the meeting will take my work and cope paste it as theirs. I really do not care.

Anyway, i know and respect everyone work, and maybe some of you really make money and live using this knowledge.

Thanks for listening and understanding.

i can only advise on rfm69 modules here
the modules come fixed to operate in one only of these bands you need one thats legal in your country
315MHz Module
433MHz Module
868MHz Module
915MHz Module

they can do FSK, GFSK, MSK, GMSK and OOK modulation
they are capable of FSK Bit rates up to 300 kb/s subject to
the bandwith / deviation selected the power level used

if you choose to have a packet radio system then the built in
Packet engine can perform CRC-16, AES-128 encyption and data whitening for you
if you network them they can also do Incoming Sync Word Recognition

and make good use of the 66-byte FIFO

they are capable of backwards compatability with older modules like rfm12b


for my network system i created a rfm12b compatable mode with a 5 byte preamble 3 byte syncword that incorporates a 1 byte net id and a 7 bit node id with a 1 bit auto acknowledge req flag , the network can transport node to node packets along with broadcast packets
it operates @434mHZ 50k deviation @17000 bps , with no encryption and a pic generated ccitt_16 crc ,it supports variable length

packets of

1-255 bytes [from memory]

reception can be polled or interrupt driven

there is no simple . I think I have three pages of possible register settings . have you looked at the data sheet or the sample code from the hoperf site ?
I got my initial rf12b system running by studying some of the Arduino libraries and adapting it to my needs

and not make you feel like you need to know rocket science to program those little modules.

it may not be rocket science but !

what did you have in mind ?

There are other modules capable of plug and play as you request. But they are not as cheap as the HopeRF are. HopeRF does really cheap modules, taking away from you all the burden of the RF circuit. Then it leaves the rest of the settings up to you, making the modules versatile as Richard described.

Also, every time the module is power cycled, it needs to be setup again, as it has no EEPROM to store the settings permanently.

If you want to have all the settings ready and just to connect it to power and a data port, then it is not for you.

These are great and cheap module but you have to do your part of the job. Can't have it all I 'm afraid.

i understand. It is not as easy as it looks like. Absolutely it is not for me. I might have to look other solutions to transfer the GPS data from one side to an other.

I thought that it wouldnt be difficult for someone, in order to help this community, to create a library and a sample program. As i said before, i understand that it takes time, and it is not worth it to make it for free.

Hi,
I don't have time at the moment to work on these type of modules, so I am using HC-12s which work fine, but perhaps not the distance.

When I get time, I hope to get SX1278 modules working, they seem pretty good, but as said previously need a fair bit of managing.

Hi camerart,

thanks for your help. But i dont think i can do anything with those modules, as i understand are not for me and my knowledge are limited.

thanks anyway.
