Ok exactly the same as mine it appears so it is strange it is not working for me... when you say... one in the loft, what do you mean?

I ordered the superheterodyne and will give it a try...

Thanks

Ok thanks Gordon. .. you mention a standalone rf module with a 50 meter range you use, Do you have a link for that to eBay?

For instance I have (pir) sensors from an alarm system I bought long ago but never used. With espruino I can analyse the rf pattern and use that specific protocol which I can already. There might be other rf devices with other protocols but it is possible to decode these too. So I have too be able to adapt to different protocols according to external devices.. this is why SPI, serial and others might not suit that well but I might be wrong (I hope)

Thanks DrAzzy

If required I am willing to use SPI or serial it is just adding more complexity and I am not sure how to proceed 😞 as I will have many RF devices each requiring their specific protocol

Hi all

Can someone provide a link to a rf 433mhz module (rx & tx) , no SPI, just a simple module that works and actually gives a range of 30 metres as often promised. I am kind of stuck at the moment, nothing really succeds and it is essential to be able to communicate across components if wanting to make any use of espruino and devices.

Any help much appreciated :)

I would be glad if anyone had any experience they would share..

Thanks

Ok but it seems like a jungle... how to spot Lora modules without decoders? Does anyone have suggestions to modules?

Thanks

Ok so analyzing remote controls and then afterwards trying to imitate this is not possible?

Thanks

Could anyone suggest an affordable rx and tx 433 mhz with a long range, maybe a transceiver- even though I am not entirely sure how to solder as they appear to have other pins.

Thanks

Yes, I do fear the soldering - I have my doubts as to the quality of my recently bought soldering iron? I am having a hard time to make it melt the solder it is 30 W.

Thansk again DrAzzy

The pads for the battery connector are hopelessly munged so it seems I should go for R9. Does it equal #4 on page http://www.espruino.com/EspruinoBoard ? So I solder the + of a new connector to the pad closest to USB and the - to ?

If I do so I will get what the old battery connector had (fet, 1A self-resetting fuse etc.)?

Thanks for your help

Will so, However I had to remove the connector because when soldering the wire to the existing connector I got a loose connection that kept switching the battery on off. Could some of the pins be used for battery with the functionality of the regulator?

Hi

My battery connector broke. I was trying to solder an additional connector (different kind) on top of the existing one and in doing so damaged the existing one and the connection to the board. Is there any way I can solder on the batteries to the board and keeping the voltage regulating function intact?

Thanks...

Ok so I found some images where I could see where to attach the antenna - but it did not change much. I have used the same length as for the transmitter.

Could it be that both the transmitter and receiver is close to each other (would like to have both tx and rx functionality on same Espruino board) and thereby generating noise of some sort? In the tests I have not used the transmitter at the same time as receiver however both is powered.

Could it be I need thicker wire as of now I just use the thin wires that came along with my breadboard.

Thanks...

Now that I got the transmitter working - I now face problems with the receiver and this time I do not see an antenna hole. When using 5 V I get a lot of signals into the receiver but I am able to deciffer the signals that I want so I can see whenever I push the remote for the sockets or when my pir sensor (almost forgotten from our old alarm system) is activated - the on / off pattern is recognized - all fine, however, only when transmitters are close to receiver. Again I expected 30 metters to be the standard but having a distance of 3 meters is the limit.

Thanks...

An update - the antenna made a difference and it now works. 17.3 cm wire is required if anyone is interested.

Thanks for your help.

Hi Gordon

Actually, there is a hole labelled 'ANT' so I guess it is required then? I will try it out.

I have the wifi device cc3000 on the other BAT pin does that affect the transmitter on the other BAT pin somehow?

Thanks again :)

Yes, I got the 'training burst' from forum - I found out it was not needed anyway, so now removed. However, the transmitter I am refering to in comment 1 appears not to have a far range. Now that I have 2 socket running and working with Espruino (well almost) the distance between transmitter and sockets is now to far. I thought a distance of 30 meters were to be expected but just 3 meters seem to far away, could this really be? The remote is powered by a 12 volt battery so a great deal more than the 4.7 - 4.8 volt from Espruino, could this explain it?

Thanks

Ok, so got it working and now able to turn light on and off with espruino.

When doing the analysis with Espruino, to find the bit patterns, I did not notice any section that could be interpreted as the "training burst" - I know it does not work without it but I just do not see why I have to add it if the signals from the remote did not show it?

Thanks..

Hi

As I am planning to have Espruino powered entirely by solar panels and batteries I would like to know if there is any way to power down external devices such as the cc3000 or a 433mhz radio transmitter when not in use in order to save batteries.

As devices is powered by vbat or 3.3v could there be a kind of switch on/off function for those pin headers? What will happen when Espruino goes into deepsleep mode? How will that affect the powering of external devices?

Thanks again

Thanks Gordon - the actual problem was a solderless pin header that did not make a connection proberly - now soldered and giving bursts of data :)

Hmmm, tested it with vbat (bat) and it did not change a thing - I measured around 4.7-4.8 volt. I have tested with several receivers (to my surprise I bought 5 pieces instead of 1). Transmitter has a 12V and 23A battery so maybe signal is not weak but I have no means to measure this.

Thanks

Thanks again DrAzzy

Hi

I have been trying to do this http://www.espruino.com/Remote+Control+Sockets , as to the receiver part for detecting the signals sent from the remote control - I have been using the suggested code. I get no response at all and can not see any bit patterns - why is that? The receiver I use is this http://www.ebay.com/itm/433Mhz-RF-transmitter-and-receiver-link-kit-for-Arduino-ARM-MCU-WL-GOOD-QUALITY-/121131013642?pt=LH_DefaultDomain_0&hash=item1c33f8960a and I did notice that the receiver has an Working voltage: 5.0VDC +0.5V so hopefully this is not the reason I can not make it work - what might be wrong?

Thanks...

Problem solved... it appears that Europe has additional channels to use, and I had selected channel 13 (less used in the neighbourhood ) which is not supported by cc3000. I have now a channel below 11 and it now works.
