LORA and Radio frequency for those who care ;)
Hi all, I started to work on a LoRa (https://www.lora-alliance.org) gateway for SmingRTOS. I’m using the RadioHead Packed Radio implementation which is in my opinion the most complete implementation in terms of functionality and device support.
I “ported” the lib to RTOS and made a first sample project.
Now i’m wayting for the LoRa devices from aliexpress (http://www.aliexpress.com/item/Upgrade-version-LoRa1278-4Km-100mW-High-sensitivity-sx1276-chip-FSK-Lora-long-range-RF-Wireless-Transceiver/32276300110.html)
If you like to have a look check my repo here https://github.com/harry-boe/SmingRTOS/tree/feature/LORA_RF95

Unfortunately nothing tested yet! It’s integrated with the SPI stack but does not support interrupts for the client (i.e. it’s polling).
I’m going to ad specific SPI slave features/interrups when i get the devices

We are already paying 10$ per farm for just basic Network . İf İ make Network with lora İ will use it

sounds interesting - never thought of it in that way - rather a normal consumer in a city

You can also create a mash network to bridge longer distances. That supported by the radio head lib

I need some help - experiencing a strange issue with rBoot + RTC + temprom.
When using the rBootHttp.. update with the same rom.bin and spiffs.bin everything can be update several times in a row and there is no problem. The spiffs.rom can change and no problem updating either. But once I recompile the rom0.bin (with little changes) - the rom won`t boot anymore.

I caught a little bit of log, but I can`t make any use/sense of the output before the reset:

Anyone experienced something similar? Do I need to change any adresses in the linker files?

Another note: flashing the new rom via serial results in a proper booting rom.
And OTA the same rom, that has been flashed also works fine - but not when the sourcecode was modified slightly and recompiled (no changes in regards to linkerfiles or makefile options)
