Lora support on OpenWrt devices via Mikrotik R11e-LoRa8 mini-PCIe card?

Hi,
did anyone try to get Mikrotik R11e-LoRa8 mini-PCIe Lora card working on OpenWrt?
Mikrotik R11e-LoRa8 is using Semtech SX1301 chip.

Are there some other Lora cards that work on OpenWrt?

Hi,

Sorry for reviving this old post, but I got my hands on the wAP LR8 kit, which is basically a wAP R bundled with the R11e-LR8 card.

First, I just added support for the router. It's not merged upstream yet, but I'll be opening a pull request soon.

Second, the R11e-LoRa8 mini-PCIe is not really mini-PCIe. It has the mini-PCIe form factor, but it uses the USB lines to communicate with the SoC. As MikroTik states:

R11e-LR8 is a new concentrator Gateway card for LoRa® technology in mini PCIe form factor based on Semtech SX1301 chipset. It enables LoRa® connectivity for any MikroTik product that has mPCIe slot with connected USB lines.

I got the R11e-LR8 detected on the USB port:

I couldn't do anything useful with the device, but at least I know it's actually accessible.

Cheers!

Upon further searching the Lora device should be able to be used with

and

and

Or even just the radio card - R11e-LR8 with a miniPCIe to USB adapter and installing packet_forwarder
from

support doc from MiktroTik
https://help.mikrotik.com/docs/display/UM/R11e-LR8

Hi Mark,

Thanks for your pointers. The R11e-LR8, which is included in the wAP LR8 kit is based on Semtech's SX1301 gateway chip, which is commonly found in LoRaWAN gateways.

I didn't have time to investigate further but I could check that the OpenWrt-based Dragino LPS8 runs /usr/bin/lora_pkt_forwarder (presumably from the repository you linked above).

Whenever I have some time available I'll try Xueliu's OpenWrt LoRa feed you linked above, it looks very promising. Do you have any experience running this software on OpenWrt?

Cheers!

Hi, no not as yet, but will do eventually when I have some OpenWRT based hardware

​i am currently experimenting with these ESP32 based devices
interfaces over Bluetooth, usb and wifi

I think one of the Xue Liu packages is in the official feeds of OpenWrt, did you see this? https://github.com/openwrt/packages/blob/master/net/lora-gateway-hal/Makefile

also ther was a work in progress PR to integrate the lora_pkt_forwarder in official feeds here https://github.com/openwrt/packages/pull/13379

yes i saw that recent lora-gateway-hal master commit

what i do not see at the moment, is many options for using lora (on OpenWRT) without using the things network - packet broker - things ecosystem

https://www.thethingsindustries.com/docs/reference/packet-broker/

the metastatic projects is very interesting as is have some very practical applications - ie remote gpio read and write

off-grid use

Did anyone look into porting basicstation (at least LNS) to OpenWrt?

@aparcar , not sure if anyone has, are you interested ?

Yes I think I'll take care, maybe @rogerpueyo can help me a bit

Hi,

@bobafetthotmail I hadn't seen neither the lora-gateway-hal package nor the PR before, thanks! :slight_smile:

@aparcar I added Xue Liu repository and compiled the packet forwarder LuCI app and the packet forwarder daemon. I got it working but, as soon as a LoRa packet arrived, the daemon crashed. Let's see if we can push it a little bit further.

@rogerpueyo I'd use the basicstation rather than the legacy pkg_forwarder, did you try that? The setup is a bit more complicated I tested it locally and it forwarded more than one package!
