Artemis and RadioHead library

Development Boards Artemis
1

Hi all,

trying to use the RadioHead library with an Artemis board, using Arduino. The low power aspect of the board is great, because I’m going to use the device as a remote outdoor weather station. I’m using a HopeRF95 LoRa board. I am able to get communication going with RadioLib, but not RadioHead.

I seem to be getting into trouble with the mBed core. I already had to alter my code because mbed doesn’t support a float into a String. That’s ok, there’s an easy workaround (I multiplied the float results from the sensor so I was working with an integer.) However. it looks like the SPI functions are different-- below is just a snippet of a couple of pages of error messages at compile time. Suggestions (other than using a different library) would be welcome. RadioHead is preferable for me because I want to be able to communicate directly and exclusively with individual modules and addressing an individual node looks easier. Error msg below. Thank you in advance. //Ed

It looks like that is an incompatibility between that library and mBed OS…try updating the board efinitions via arduino IDE https://github.com/nRF24/RF24/issues/537 and re-try?

3

Install library version 1.2.3 and these calls are still accepted in this library version. The biggest aspect you lose in a default configuration is BLE.

thank you both for your input. Regrettably, neither suggestion worked. I’ll use a brute force hack with radioLib.

5

out of interest: what did not work ? Was the setBitOrder call not found ?

Thanks for the replies–

sipan1313-- thanks for the general info. I was aware of the need for two objects for the code to work. I usually run an example before I start coding my own project. The compiler failed to compile an example sketch; I don’t remember exactly which one.

paulvha-- error dump below. The compiler was exceedingly unhappy… I’m a decent intermediate grade programmer but not the most savvy by any means. I depend on libraries a lot so I don’t understand all of the subtleties. However, after doing some research and reading, looks like the problem is with the mBed core not supporting all the SPI functions. I would not know how to alter the code to make this work.

FWIW, I ended up using the LoRa library by Sandeep Mistry. Easy to use and seems to be reliable. I had to add some simple extra message filtering code to allow addressing a single unit out of three deployed, but that was a lot easier than messing with the hardware interface. Appreciate your interest.

where can I find the library you use online? Maybe I can some changes to make it work

Here’s the URL. http://airspayce.com/mikem/arduino/RadioHead/

Thank you for your offer to correct the code. If you want to pursue that for your own interest, that would fine, but it’s not a must have at this point.

My new approach is working well, and I don’t need to go back to this library.

The RadioHead library is quite robust. If it worked for the Artemis community that would be a plus.

Best regards,

Ed

I have made 2 changes to get this to work, It now compiles without errors.

One disadvantage RH-ASK is not supported, but I expect a low impact for most users :

RH_ASK Works with a range of inexpensive ASK (amplitude shift keying) RF transceivers such as RX-B1 (also known as ST-RX04-ASK) receiver; TX-C1 transmitter and DR3100 transceiver; FS1000A/XY-MK-5V transceiver; HopeRF RFM83C / RFM85. Supports ASK (OOK).

wow, thank you. I had not been back to this forum for several days. I’m sure this will be useful for me and others. Can’t wait to see this compile.
