Built for software platforms
The GBL-SL4G connects to your backend over HTTP or MQTT. Your server sends a command and the device acts - no driver, no local agent, no network to provision.
Desktop scanning, no host required
With its own 4G link and an angled scan window, the GBL-SL4G reads 1D, 2D and on-screen codes at the counter or kiosk without a connected PC, and caches scans through brief network drops.
One API for the whole fleet
Device registration, online status, remote configuration and firmware updates all run through the same OpenAPI surface as every other Gobilink device, so adding the GBL-SL4G is a configuration change, not a new project.
