Awesome video !! I like the format of your tutorials ! Could you also post details/links on the products you used ? That makes it easy for the viewers.
Great work! Curious about sending GPS NMEA over LoRa using the Ebyte E32 modules and maximum range at 9600 baud. This could be a very interesting project for the hobbyists
Great videos, it's really helping me understand these Ebyte E32 modules and LoRa! I'm guessing the code for Cog #2 essentially just writes to serial whatever it reads? What are your thoughts on LoRaWAN?
Yes .. Cog #2 is used as a store and forward device and sends what it has read. Here in Canada we do not have any LoRa gateways unlike some European countries where LoRa and Sigfox are gaining popularity so I use LoRa as point to point radio links. I do not see LoRaWAN taking off here as we are using cellular based CAT M1/NB-ToT instead, as the cellular infrastructure is already in place. www.sparkfun.com/products/14997 For LoRa networking check out my video on LoRa over Ethernet. czcams.com/video/g9nNff6wknY/video.html
Good day, did you make the test of the repeater? very interesting project. Could you explaind more in software how to make the fixed mode to the repeater :D
Great stuff. Where do we start getting into that thorny land of FCC regulations? I assume you are focused on the power and band regs. Does a “network” of otherwise exempt devices bring us into an area where a license is required? I am absolutely not suggesting I know the answer or that, as hobby/non-commercial guys we should worry too much.
The LoRa modules work in the ISM band which is license exempt. As a hobbyist we can play with them and use them in our projects. They are FCC certified with a FCC ID number stamped on the module. The FCC certification is honored in Canada. If you want to sell a product containing a LoRa module that is a different story. You have to get your product tested and certified by a certified lab which will issue you a FCC ID number in the USA and a IC ID number in Canada. This number has to be applied to your product. Your customer does not need a license but if it interferes with a licenced user the product has to be shut down.
use software serial and you will have as many serial ports as you desire on a nano or any other microcontroller. i use an adafruit feather to drive dual rs232 using hardware and softwareserial and it is trivial to use. swapping the mcu was totally unnecessary.
Are you running multiple software serial ports at the same time? I would be interested to see that. Can you send me the link to your video. www.arduino.cc/en/Reference/SoftwareSerial
SoftwareSerial.h is used in the videos. At 24:13 he is sending data to each serial port (4) in sequence 0,1,2,3 not at the same time. I need to receive serial data on all ports SIMULTANEOUSLY not one at a time.. If you look at the "Limitations" on the website you will see: The library has the following known limitations: If using multiple software serial ports, only one can receive data at a time. www.arduino.cc/en/Reference/SoftwareSerial
I may be a dumb old guy from the 8080 days. That said, if I’m not mistaken, the multi port library has poor to no synchronization options for asynchronous communication between multiple micros. I have been able to do async on a single micro system. But even that was basically brute force software based forced async. A single interrupt causes the system to do caches or complex poling or something equally distasteful. Where Have I gotten off track.
@ms3bani, The Propeller definitely makes sense to use for something like this. Each cog can process one of the ports in parallel and the code will actually be simpler than trying to multiplex all of the reads/writes, as well as easier to scale up/down (just start/stop cogs). Sure, you can handle multiple UARTs on an Arduino, but you can also insert a screw with a hammer if you try hard enough. That doesn't mean it's the best tool for the job.

wow you need a whole MPU core just to do serial? how bad is your coding!!!!! you can add software serial to most arduino for debugging at the like... probably even good enough for multiple LoRa devices
Are you running multiple software serial ports at the same time? www.arduino.cc/en/Reference/SoftwareSerial I have to run a operating system with an on board compiler at 230400 baud with six serial ports at the same time. I would be interested to see your code.
1980s electronics technology presented by Christopher Walken. Surreal stuff.
Oh, wow. I have a couple of Propeller Quickstart boards but I've never seen the FLiP before. Your channel is great, btw
Thanks for the feedback!
Very cool... Very interesting project. I am anxious to keep up with this progress.

wow your videos are so interesting
Thanks for the feedback!
Great video and presentation. Could you point me to the code you used to make a LoRa repeater with the Pro mini, not the propeller?
Great work! Curious about sending GPS NMEA over LoRa using the Ebyte E32 modules and maximum range at 9600 baud. This could be a very interesting project for the hobbyists
Yes .. that would be a good application. I am planning on using a GPS in the LoRa project.
AVE? Shhhh!

could you adapt this Repeater to work on a Bobcat miner 300 ?
No, it is not compatible with the LongFi protocol.
Good day, did you make the test of the repeater? very interesting project. Could you explaind more in software how to make the fixed mode to the repeater :D
Check out this video that covers fixed mode. czcams.com/video/JvBC7cEgI0E/video.html

Podrías poner el código, quiero hacer ese repetidor
Pudiste lograrlo? yo tmb quiero!
Very very cool
awesome
where is all the code ?
The code is basically a FIFO buffer which can be written in any programming language.
