TTN 1ch gateway, modif to 433Mhz
I have made a 1ch TTN gateway with the my heltec lora oled modules on hand. 1st, I found an working example with my boards from TTN forum: info are here: http://ldsrc.blogspot.tw/2018/01/lorawan-working-example-from-network.html The major work of 1ch gateway is from here: but in the forum has better steps. http://things4u.github.io/ https://github.com/things4u/ESP-1ch-Gateway-v5.0 For gateway: 1. So, what I did to make it to 433Mhz, is to modify the frequency table in loraModem.h to like this: /* int freqs [] = { 868100000, // Channel 0, 868.1 MHz primary 868300000, // Channel 1, 868.3 MHz mandatory 868500000, // Channel 2, 868.5 MHz mandatory 867100000, // Channel 3, 867.1 MHz 867300000, 867500000, 867700000, 867900000, 868800000, 869525000 // Channel, for responses gateway (10%) // TTN defines an additional channel at 869.525Mhz using SF9 for class B. Not used }; ...
