Rattlegram vs MeshCore One

COFDMTV is based on COFDM (coded orthogonal frequency-division multiplexing) technology: - 160 ms long OFDM symbols - 6.25 Hz per sub-carrier - 1/8 guard interval - differentially encoded PSK (phase-shift keying) modulation - systematic polar codes for forward error correction Currently Modes 14, 15 and 16 are supported: Using either SPC(2048, 1392), SPC(2048, 1056) or SPC(2048, 712) with CRC32C aided SCL decoding and differential QPSK modulation for the payload. Only a bandwidth of 1600 Hz is needed and the transmission of either 85, 128 or 170 bytes take about one second with the leading noise and fancy header disabled.

MeshCore One lets you send messages over the MeshCore radio network: long range, low power, and completely off the grid. No cell service, no Wi-Fi, no accounts, and no internet required. Just your iPhone, iPad, or Mac and a small MeshCore radio. Whether you're hiking a back-country trail, working an event, out on the water, or keeping your group connected when the power's out, MeshCore One keeps everyone connected. Messaging - Direct messages with delivery status - Group channels, reactions, and mentions - See the path each message took across the mesh Map - See where your contacts are - Standard, satellite, and hybrid map layers - Download map regions to work offline Contacts - Share contacts by QR code - Favorite the people and nodes you rely on - Automatically discover other radios nearby Network tools - Trace paths your packet takes - Line of Sight and terrain analysis to plan your coverage - Live signal and noise monitoring - CLI to manage repeaters and rooms Remote nodes - Check battery, uptime, and telemetry on your repeaters - Configure and reboot nodes from anywhere on the mesh Your Privacy Comes First MeshCore One works entirely offline. There are no accounts, no servers, and no tracking. Messages route directly between devices and never touch the internet. What You Need - An iPhone or iPad on iOS 18 or later, or an Apple Silicon Mac - A MeshCore-compatible radio (such as a Heltec V3 or RAK WisMesh Tag) running MeshCore firmware Connect over Bluetooth or Wi-Fi, pick a radio preset, and start messaging across the mesh.
