Any chance there’s a fritzing part available for the Makerverse LoRa-E5 Breakout?

Hey @Matthew16091 - welcome to the forums 
There isn’t yet! We don’t have any immediate plans to make one either.
If you’re interested in making your own
This is an open source project though - If you’re curious about making your own fritzing model you could export .SVGs from the KiCad project (repo) and try your hand at making your own fritzing model (tutorial)
There’s also the official Fritzing page for making custom parts.
If you take the plunge, let us know and we can add it to the repo or you can submit a pull reqeust.

Hi Dear, just wondering how setup this lora module on raspberry pi 4 and esp8266. I had tried and didn’t work. Any help?

Hi Gunawan,
ESP8266: First you’ll need micropython on your board of choice, load on the example code (you might have to change the TX and RX pin numbers) and it should work straight away.
Pi: there aren’t any dedicated instructions but the example is written in python which should be easy to adapt with a bit of help from ChatGPT,
Keen to see your project come together!

Using this module for sending RTK GPS base corrections.
Is there anybody out there who has some experience with using LoRa-E5 for this purpose. I think the module needs to be re-programmed to be able to send larger data packets.
I have found a few links on this path but need some pointers on how to go about this with this particular module.

The problem is the AT command is limited to abt 500bytes. The RTCM corrections are a continuous stream.
The other thing is I do not really want to use another mcu to communicate with the E5 module. It has a mcu already in it so would make sense to use that… if I can work out how to program it and upload arduino code.
Hoping someone out there has done this ?

Hi Don,
Its definitely possible but you a much more advanced feature than using the base AT command set.
A separate parsing microcontroller would definitely be the easy way out!
I’d check out Sparkfuns RTK range to see how they manage to send the base station corrections: https://core-electronics.com.au/catalogsearch/result/?q=rtk

Hello Brains trust, has anyone used these lora units to do point to point over a bit of a distance. The best I can get is around 865 metres on SF9 and power of 22(max), I was hoping to get around 1.3k but i suspect my antennas are letting me down (just indoor 1/2 wave 2dbi antennas). I’m just sending ‘01’ in hex so not a lengthy packet size by any means, I’ve tried going up to SF12 but it doesn’t seem to help me any. I’m thinking of trying yagi antennas at each end next.
Any help would be appreciated.
Thanks, Brett
Hi Brett,
Antenna placement and quality are what come to mind for getting better signal strength.
The higher you can get the antenna above the ground and away from objects the better and moving to a more directional antenna even on one end may help as well.
The other thing I think could be causing issues could be interference from other devices in the 915MHz band. without having a spectrum analyser it may be hard to determine if this is definitely an issue though.
Hi Brett
Have you tried moving further away or did you stop when you ran out of steam.
As I have said 900MHz can be a strange beast. If you have a reflected or scatter signal which happens to be 180º out of phase and enough amplitude you can have complete cancellation. If you move further away or higher and get an improvement this will almost certainly be the case.
Antenna positioning will be all important here and you hope the interfering cause does not move. If it does you might have to start again.
Of course the reverse is also true. You can have an interfering signal in phase where you will get a level increase. After all this is how a Yagi works.
Cheers Bob
This is assuming clear line of sight. If you have any obstructions or hills all bets are off.
Thanks Aaron, yeah that’s possibly why my test at home went well, I drove up to the next estate where it was pretty high. I’m 60 k’s out of town in central Qld so I’m hoping there wouldn’t be too much interfering with it, I might look at changing the frequency next, see how that goes. Thanks for getting back to me
Cheers

Hi Bob, 865 metres was as far as I got at home, out here I think we managed to get close to that, I’m just going to go test again after setting pre-amble to default as I had them set to 12 & 15 (as per the Lora -E5 command info doco), just in case that is messing with it? There is an intrusion fence running down the length of the driveway so possibly could be adding some reflection in there. There’s not much between the gate and his house, but yeah a bit of height would be good. So do you think a yagi at each end would be beneficial?
Cheers,
Brett
Hi Brett
Won’t comment on that without eyeballing the situation as RF and as I said 900MHz can be tricky. Yagis would not hurt but you need to keep any connecting cable very short or you will lose most of your signal here. If you need to go up you will probably have to put the electronic bits up there with the antenna.
One of the last times I had much to do with 900MHz was a troppo scatter system. 193km, 10W but using very low loss Andrews co-ax 1 5/8 inches diameter and antennas with 30db+ gain. Even this required a quad diversity system with 2 transmitters and 4 receivers at each end.
Cheers Bob
Thanks mate, yeah that shouldn’t be a problem, the receiver is already mounted at a reasonably height, we’ll just have to figure out something for the tx end.
Tropposcatter hey, sounds complex alright 
Cheers
Yes. RF has its moments.
Cheers Bob
A bit of an update on my project, having a yagi at either end dramatically increased the db level and range, could get 1.6k easily, time to plan another trip out west 
1 Like
Hi Brett
Good news.
The 2 go hand in hand actually. The db increase should theoretically be the gain of the Yagis minus any loss for extra cable. The cable loss could be significant and depends on length (mainly) and type and quality.
Lets hope your scenario out west does not introduce any more funnies likely to degrade your present performance. With a bit of luck you could well see a bit of enhancement.
Cheers Bob
Yeah I think I should be fine, will take another yagi out there with me, if needed I can place one either end. I had pretty good results, -70db at 1.6k. And yes, I took your advice and kept the coax short (900mm). I’ll publish the project when I’m finished, I’m adding a few extras like a clock source so his gate will open and close at particular times, plus a web page so they can open it via a web page if needed. Cheers
