Esp8266 meets LoRaWan
I guess that you don't have any doubts that ESP8266 can do LoRaWan.
For this project I've used two modules:
1.LoRaWan Single Channel Gateway
Single channel gateway ( to be compatible with LoRaWan you must have 8 channes) was made using the SX1276 module and a Raspberry Pi2. Comunication is done over SPI using wiringPi library.
2.LoRaWan node with ESP8266
For node I've used the Witty module with the modifications from this post.
As a software I've used the ported LMICv1.51 and modified to send data to only one channel since the gateway is single channel ( I am using 868.1Mhz).
Now the gateway is enrolled in TTN ( https://thethingsnetwork.org/) and the data has started to arrive. I've managed to receive also data from other surrounding nodes.
On the gateway data looks like:
Packet RSSI: -107, RSSI: -105, SNR: -11, Length: 108
rxpk update: {"rxpk":[{"tmst":368384825,"chan":0,"rfch":0,"freq":868.100000,"stat":1,"modu":"LORA","datr":"SF7BW125","codr":"4/5","lsnr":-11,"rssi":-107,"size":108,"data":"Wqish6GVYpKy6o9WFHingeTJ1oh+ABc8iALBvwz44yxZP+BKDocaC5VQT5Y6dDdUaBILVjRMz0Ynzow1U/Kkts9AoZh3Ja3DX+DyY27exB+BKpSx2rXJ2vs9svm/EKYIsPF0RG1E+7lBYaD9"}]}
and data from my nodes:
Packet RSSI: -28, RSSI: -105, SNR: 12, Length: 31
rxpk update: {"rxpk":[{"tmst":1060664170,"chan":0,"rfch":0,"freq":868.100000,"stat":1,"modu":"LORA","datr":"SF7BW125","codr":"4/5","lsnr":12,"rssi":-28,"size":31,"data":"QGIH4AIAqgABvJNVF4DpUapp/xQN1REVnI+jYoR6Ig=="}]}
Next I'll have to add sensors to nodes and to run some tests for range and buy a real gateway.
