# ESP8266 / ESP8285 TheThings Network LoRaWAN transmitter.
|
||||
|
||||
Same as the others - connect a small length of wire to the "RX" pin on your ESP8266, then it will transmit SF7 LoRa messages at 904.1MHz.
|
||||
|
||||
But this, has the code in main() to send frames to thethings.network as valid LoRaWAN frames.
|
||||
|
||||
|
||||
On thethings.network,
|
||||
|
||||
1. Generate a new app.
|
||||
2. Register a new device.
|
||||
3. Select `Enter end device specifics manually`
|
||||
4. Select US Plan 902-928, FSB2 (Used by TTN)
|
||||
5. LoRaWAN Specification 1.0.0
|
||||
6. TS001 Technical Specificaiton 1.0.0
|
||||
7. "Show Advanced activation, LoRaWAN class and cluster settings"
|
||||
8. Activation by Personalization
|
||||
9. No addtional LoRaWAN class capabilities (class A only)
|
||||
10. Use Network's default MAC settings.
|
||||
11. Generate new EUI.
|
||||
12. Generate new Device ID.
|
||||
|
||||
Add the device, it may make sense to back out to the menu so you can copy the LSB for the address, and the code for MSB for keys.
|
||||
|
||||
Replace the `payload_key`, `network_skey`, and `devaddress` in `main.c`
