Hi. I am interested in development of this dual-module board, a friend doing amateur radio pointed me to this since I have a foot in the world of radio mesh and an interest in longer wavelength comms. This runs the disaster.radio firmware normally loaded onto those Ali-vendor sold TTGO LoRa modules?

Yes, the current firmware runs on TTGO LoRa32 V2.1 ESP32 OLED 0.96 https://item.taobao.com/item.htm?id=592989061028 Generally, I think the firmware should work for these boards http://www.lilygo.cn/products.aspx?TypeId=50003&fid=t3:50003:3 On 2021/5/6 下午12:06, Code Bus wrote:

Hello, first: thank you for all your effort! I really like the idea to transfer short messages over longer distances. So I bought 2 LILYGO®TTGO Katastrophe-Radio LoRa32 V 2,1 1,6 Version 433/868/915MHZ LoRa ESP-32 OLED 0,96 Inch SD Karte Bluetooth WIFI Modul as I was told there https://disaster.radio/ I tried them but the text i inserted into the chat didn't appear in the other device connected via wlan, not even when i connected both wlan devices to one of the two wlans What am I doing wrong? A functioning firmware should be on them. Kind regards for any hints or clues in advance. mhf On 06/05/2021 07:29, Wensheng Xie wrote:

I think they are asking specifically for a dual-LoRa device. If I understand correctly, Fitz has a handful(?) of dual-lora prototype boards that may or may not work with the current build of the firmware (likely it would need some tweaking of pins, etc. since I never got my hands on one for testing). I did some hacking last year on a dual lora setup. I'm pretty sure I used the LoPy4 and an old-school ESP8266-compatible disaster.radio LoRa hat (what's up from 2018! idk if anyone else still has any of these...). I used the LoPy4 because other boards don't break out all the pins needed for the dual-lora setup. The point is, i was able to get two lora modules connected to an ESP32, but I didn't do much more than that. Fitz, I'll DM you about getting at least one of those prototypes sent my direction so I can validate that it works with the firmware (idk how soon I'll get around to it, but eventually). -Grant On 5/6/21 1:29 AM, Wensheng Xie wrote:

Correct, I was replying to Fitz's call to those interested in developing the device. My makerspace in New York has an ESP32 board that I could integrate with this if it is just the LoRa modules. May 6, 2021, 21:43 by grant(a)peoplesopen.net:
