BLE bugs are platform-specific. Prove your peripheral works on real hardware - from one page.
GattLab dispatches a plain-YAML test contract to real Windows, Android, and iOS devices sitting next to your peripheral, and reports back a step-by-step PASS/FAIL - no walking between devices, no GATT commands to remember.
The problem with testing BLE peripherals today
"Works on Android, fails on iOS"
Platform-specific BLE stack differences surface late, often only once QA or a customer hits them on a device you didn't test.
Verifying a firmware change means walking around
A one-line firmware fix still means physically visiting every test device and tapping a button to re-check it.
Results are screenshots and memory
Without a shared, comparable result format, "did this pass last week" is a Slack search, not a query.
How it works
Install & log in
Install GattLab Agent on each Windows PC or Android phone you test with, and log in with your GattLab account.
Write a contract
Describe the expected behavior - advertised name, required service, characteristic writes - in plain YAML.
Dispatch & read results
Run it against one device or a whole fleet and watch step-by-step PASS/FAIL come back live.
Only one agent talks to the peripheral at a time - fleet runs are dispatched sequentially, since most BLE peripherals only support a single connection.
What it checks today
Discovery & connection
Advertises with the expected name, and a connection succeeds within a configurable timeout.
Required service
The expected GATT service is present after connecting - the actual UUID mismatch is reported when it isn't.
Characteristic reads/writes
Write bytes to a characteristic and assert success, or assert an expected response via a read-back or a notification.
Honest scope
Not yet supported: advertising interval/RSSI assertions, MTU and connection-parameter checks, indications and descriptor reads, background execution, and multi-connection scenarios. A BLE sniffer mode and a drag-and-drop simulator mode are on the longer-term roadmap but not part of this build. See the contract reference for the exact current step catalogue.
