Posted at 2017-03-12 by oesterle Off the the top of my head, I'd say it's doable on nRF52. Other questions would that would guide one in selecting hardware: Do you want to forward packets from LoRA, BLE, or both? Posted at 2017-03-13 by OwenBrotherwood The current status of TTN kickstart GW is no known delivery date which means I have to go to plan B: the "standard" Pi / ic880 : ie multi-channel. So step 1 is get backing for the gw's: 4 to cover https://www.thethingsnetwork.org/community/silkeborg/ around the hills of the valley that is Silkeborg (history started with water and the production of paper). step 2 is make one GW with Pi for presence step 3 is a bit of play and learn (nRF52 (puck.js) instead of Pi) with some tests: limited time as a constraint so that may not happen until more time and extra ic880 step 4 with regard to time constraint, use what I have gotten so far for the other 3 locations (my house is location 1 as it is has height and internet with clear sight over Silkeborg to the other locations) The Pi has everything, including the kitchen sink and an SD card one has to be careful with in connection with corruption with power loss (solved by R/O SD access). It has IP connectivity (Ethernet and wifi). The answer is, "it depends" I know: is it "play and learn", probably. (off to a meeting today to see if I can get backing) Posted at 2017-03-13 by @gfwilliams Looking at the LoRa stuff, it sure seems like you could run a packet forwarder on Espruino. nRF52 could easily forward BLE data over an RN2483 to a LoRa gateway, and could do so while using relatively little power. Trying to make a gateway itself could be possible too, maybe - but I see that being a lot more work, and personally I think it'd be worth leveraging the existing work done on the Raspberry Pi version. Posted at 2017-03-13 by OwenBrotherwood "Stuff" is on it's way: I tend to buy from people and not companies. Pi will be production: nRF52 is going to be interesting.

And it would run Espruino :) Doesn't say which nRF51 it is - there may be very little memory available for code - made even more difficult by the way the LoRaWan protocol would need implementing in it too. I wonder if they're releasing an nRF52-based one - that could be a really useful module. Posted at 2017-03-15 by OwenBrotherwood Yes: but on the other hand, there is a guy in Belgium that may be joining the Espruino for tangental interests and allow for some cool things. Posted at 2017-03-15 by oesterle This might also be able to run Espruino. It's ESP32-based.

In TTN (and non-TTN), many use a Pi.
I would like to use a micro controller.
Having stated this in a TTN channel, someone asked:
"Are they (red: nRF52) powerful enough to run a packet forwarder? I'd rather use an ESP8266"
Two things here could be the hardware and the software.
From the point of hardware, and comparing apples with oranges, is there a golden bullet that says one contra the other?
