t-beam

LMIC-node | One example to rule them all. LMIC-node is an example LoRaWAN application for a node that can be used with The Things Network. It demonstrates how to send uplink messages, how to receive downlink messages, how to implement a downlink command and it provides useful status information. With LMIC-node it is easy to get a working node qu…

TTNMapper on the TTGO T-Beam

EByte module flow-controller does the store-and-forward task so that the packet dropping, due to the congestion between microcontroller and Ebyte module, be reduced.

with ESP32 based T-BEAM, a LORA communication between 2 T-BEAMS. Sender sends to receiver, and receiver acknowledge message

A simplified “PingPong + recovery” sketch, based on RadioLib example

Multihop Data Relay Implemented on TTGO-T-Beam -- The LoRa Module

Off-grid group chat and a shared live map. One ESP32-S3 board is the whole network — no internet, no server, no cell. Early prototype.

Testing of setup of GPS module for an Lilygo T-Beam

T-Beam blocks direct PC access to the u-blox NEO-M8N, but analyzing ESP32↔GPS traffic needs PYGPSClient/U-Center. A passthrough can forward GPS→ESP32 data to the PC for analysis, but can’t relay PYGPSClient config commands back to the GPS—so configuration must be done in code setup.

hot-and-cold” game gadget with 2 players, but instead of saying “warmer,” gadget simply points you in the right direction of buddy with a LED ring. compass knows which way you are facing. it can tell whether you’re pointing toward north, south, east, or west. It knows where your buddy is, Both gadget talk with off grid LORA radio.

First in setup a message from ESP32 to Ubox Neo M8N, that configures UBX-NAV-SAT messages to T-BEAM ESP32, and then in Loop, from this message a longitude and latitude is extracted. pre-work to the "hot and cold game"
