with a compatible LoRa radio
Survive Link can connect over Bluetooth to compatible LoRa hardware and hand messages to the radio. The app does not create firmware or operate an independent radio network. Availability depends on the model, firmware, configuration, and local rules.
Check model and firmware compatibility with the manufacturer before using a radio. Range and delivery are not guaranteed.
Data-capable USB cable
Use a USB cable that transfers data; a charge-only cable will not work.
US 915 region
Consult official documentation for the permitted region in your location; this handoff mentions US 915 only for the corresponding variant.
Channel-key security
Public/default channel keys are not private. A custom PSK encrypts the channel but does not authenticate the sender.

Firmware and connection
Follow the manufacturer’s instructions to install and configure compatible firmware. Then connect the radio from Survive Link’s Radio screen. The app hands text to the radio; relaying and store-and-forward depend on the radio and network. Check current regional rules for your location.
Use Survive Link’s Radio screen to connect, manage channels, and send text. For firmware installation, regional rules, or radio-specific support, consult the manufacturer. Survive Link does not distribute firmware or guarantee message delivery.
