OOK_Receiver + LiLyGo LoRa32 V2.1_1.6 + Display?

[grymoire]

Current Situation

I've gotten OOK_Receiver running, but I wondered if anyone has added display output? Essentially, it would be easier to demonstrate the program if the display showed activity.

Proposed Change

If there is a display, then show packet activity there as well as the serial log.

Additional Context

I might have several dongles plugged into a laptop. This would not only make it easier to me to keep track of activity, but it would also show others that is is working properly.

The code that drives the display is part of openMQTTGateway. Install a recent version and it will turn on

I did, and it displays "Connect your phone to WiFi OMG_ESP32_LORA"
I don't want a gateway. I don't have a MQTT server. I want a sniffer, like OOK_Receiver but I want info on the display as well as the serial port.

I've tried to add the display by copying piece of openMQTTGateway, but I could use some hints. I'm not a skilled platformio user.

The display code within OMG is actually quite complex, as it supports a lot of different message formats beyond rtl_433 and also uses internal message queuing so transplanting it from the OMG code base is very complex. But it is based on this library - https://github.com/ThingPulse/esp8266-oled-ssd1306#f96fd6a

It should be feasible to take one of the SSD1306 examples and extend it to display the rtl_433_ESP serial messages - ie the frame 4 example https://github.com/ThingPulse/esp8266-oled-ssd1306?tab=readme-ov-file#frame-4

Or to get something going quickly, install OMG - lilygo-rtl_433 and configure wifi and MQTT. For MQTT just install mosquito on a device that is always on.

PS Platformio is the preferred development IDE for coding ESP and other devices. It is well worth the effort to get familiar with.

Okay, Thanks. I'll give it a try
