I suppose you are talking about the RAK811_BrakBoard software. There, the UTC Time is available in NmeaGpsData.NmeaUtcTime.
So that is something i am curious about, is the supplied antenna specifically for 868 or is it intended for both 868 and 915? It seems that way.
I measured my set-antenna around 1.08GHz. Works great for ADS-B, not so great for LoRa...
Thanks for your reply. I found another solution: just pull up boot1, then SWD will work.
Well, I think it's like this: you send a package with confirmation. If you don't get the confirmation and try to send again, you'll get the ERROR-6. In this case, you might try to reset the RAK811-N and try to send again.
Hm, I don't know which §5 you are referring to. The RX2 is defined in Section 2.2.7 in the LoRaWAN 1.1 Regional Parameters, at least for the EU868. It defaults to 869.525MHz/DR0. BUT: In EU868, the Network/Gateway may set another channel/DR for RX2 in the Join Accept message. And for your case, you can't use RX2 as you got a single channel gw.
Hm, these MAC BUSY errors are really strange.
I don't think you are sending too fast, as I sometimes send 5 messages in 2 seconds (after hard reboot, I send the device config of the irrigation sensors which is no problem at all). So i think RAK811-N are buggy somehow...
As for developement, I'm afraid that the -N version might be the wrong choice. As you see on the following picture, there is no internal programming support:
I found this on Aliexpress.
As for the toolchain, I use GNU Arm Embedded Toolchain, at the moment without any IDE using Makefiles under Ubuntu. I simulate using qemu and I debug/programm the devices with a fake J-Link using OpenOCD.
But I think I'll give GNU MCU Eclipse a try soon. But in the end, you know, I don't like this bloatware IDEs too much. What OS are you on?
I try to provide a cleaned up template project for the RAK811 soon via github. To be honest, it's a big uncommented nearly -everything-in-one-file-mess at the moment, especially the low power states need some love.
Looks like your connection to RAK Support Center was lost, please wait while we try to reconnect.
