LoRa network setup...

[RSK]

Would like to setup LoRa netwrok as shown below,

I have LoPy 5 pack kit https://www.pycom.io/product/lopy-5-pack-pure-greed/ from making the LoRa network setup.

Planning to follow the below steps,

1. Update the firmware first in all five devices.
2. Use LoRaMAC smaple given in https://docs.pycom.io/lopy/lopy/quickref.html#lora-loramac to communicate 2 devices. To make sure that RF works properly.
3. Now try to setup LoRa gateway including wifi driver working (sample would be required).
4. Create LoRa netwrok (sample would be required).

I have completed step 1 and trying out step 2 currently.

Please let me know if the approach is correct and provide sample for step 3 & step 4.

The object is to have the IoT network using LoRa.

Or suggest some other mechanism to achieve the intent using LoPy.

Thanks sakis. Apologies - I was looking in the wrong place for the LoRa documentation - I expected it to be in the Pycom specific modules section, because I assumed that general MicroPython documentation would not contain any hardware info at all. Oops.

We've restructured our documents recently so that link is broken: https://docs.pycom.io/pycom_esp32/library/network.LORA.html
https://docs.pycom.io/pycom_esp32/pycom_esp32/lora_examples.html#lora-loramac

Next week we will do a new documentation release which provides more information about many modules, including LoRa

I can't find that LoRaMAC example. In fact I can't find ANY example code that let's me test the LoRa radio.

Hi, personally I'm happy to share the code for the IoT bike.

I need to check with my employer as technically speaking they own what we developed. I'll ask and share if I can.

However it was coded against the early beta programme boards and needs a few tweaks to run on the released boards due to the various enhancements on LoRa (found that out the hard way when I tried to update the hardware for the bike's most recent outing)

It's pretty basic (mostly coded overnight as poor Daniel will confirm :) )

@KDHeard

Sucessfully tested with two LoPy and it works good.

LoPy to LoPy TX & RX are working with LoRaMAC mode https://docs.pycom.io/lopy/lopy/quickref.html#lora-loramac

Would need LoPy gate way to add the third, fourth, fifth ....., Is there any official new on LoPy gateway firmware release.

Hey gents - not sure if you have come across this application that links 2 LoPys to a third:

@administrators : would it be possible to share the code for this with the forum?

@RSK I only have one LoPy so I can't test this myself but I'd assume this should work.

Re: LoRa network setup...

No i do not have any gateway link. Will have make LoPy as gateway to push the data to remote server.

When can i expect the firmware update for gateway support. Any tentative timeline???

Is there a way to test basic LoRa Tx/Rx operation of the LoPy device in range 865 - 867 Mhz.

Keep two LoPy device programmed with current version of firmware and make one as transmitter and other as receiver.

Referring to the sample: https://docs.pycom.io/lopy/lopy/quickref.html#lora-loramac

Will it work?

I'm assuming from the limited information provided that you intend to use the LoPy as a LoRa gateway? The current firmware does not yet support this.

If you already have a gateway it would be helpful to mention what kind of gateway that is.
