SmartTag HD110 (Type 1314, 400x300 Mono) — LED test works, image/text transmission has no effect

[vincent-bidaux]

Hi, I’ve been testing TagTinker v1.3 on Momentum firmware (mntm-012) with a Pricer F03 tag recovered from a Carrefour City store in France.

Tag info (from NFC scan):

•	Model: SmartTag HD110
•	Type: 1314 (Graphic)
•	Size: 400x300
•	Color: Mono
•	Barcode: N403132170231313143

What works:

•	NFC scan correctly identifies the tag with all details above
•	LED Test under Targeted Payloads successfully triggers the green LED on the tag, confirming IR reception is working

What doesn’t work:

•	Sending text via Targeted Payloads → tag shows no reaction
•	Sending a BMP image (prepared via the web tool with the HD110 profile) → tag shows no reaction
•	Broadcast → Change Page and Diagnostic Page → no reaction

Transmission takes ~30 seconds and completes without error on the Flipper side, but the e-ink display never updates.

Setup:

•	Flipper Zero (original), Momentum firmware mntm-012
•	TagTinker v1.3 built from source with ufbt
•	IR emitter pointed directly at the tag’s IR receiver at 2–5cm distance
•	Tested multiple distances and angles

Is the Type 1314 protocol fully implemented? Happy to help test further if you need signal captures or additional info.

Thanks for the great work on this project!
