### 1/5 — Their resolve

*2026-04-23, version 2.9.1*

**Bluetooth Security Protocol:**
1. Completely close the GLI Open
Sign app
2. Unplug your sign from the back for 30 seconds (leave the power switch ON)
3. Open the GLI Open Sign app and leave it open
4. While the app is open, plug the sign back in
5. Reconnecting should take about 15 seconds
6. **Important**: Do not toggle away from the app during the connection

### 1/5 — After update quit working

*2025-09-30, version 2.9.1*

We have the 1050b from GLI and for the first year or 2 it worked... that is until daylight savings time came and I tried connecting to the sign to update the time.  When I opened the app, my sign was not listed on the “nearby device” list. I tried uninstalling the app, I unplugged it and plugged it back in.  Still don’t work.  I spent $200 on a sign that now turns itself off and on over 2 hours earlier than I want it to.  It’s extremely disappointing that Apple allows company’s that don’t back there product to put apps on their store. I've tried contacting the company's customer support which is non existent. Or they just don’t care to respond.  I would return the sign before it’s too late.

### 1/5 — needs to be worked on

*2025-03-11, version 2.8.1*

it would be nice to rename signs to tell the difference between two signs.   app is really struggling to update them both

### 1/5 — Update fix it?

*2025-02-08, version 2.8*

Need to update the app , can’t update the hours

### 1/5 — Scan it gets to scan and freezes up won’t do a thing

*2025-02-04, version 2.2*

Doesn’t work at all

### 1/5 — Bluetooth not working

*2025-01-26, version 2.2*

App not working at all can’t connect at all old app was good new update no good

### 1/5 — Can’t see the sign

*2024-11-13, version 2.2*

Scan can’t see my sign

### 4/5 — Simple time adjustment

*2024-11-02, version 2.2*

We are enjoying two signs. When it comes to daylight savings and fall back we simply open up the app, connect to each sign and it syncs with the updated time on my Iphone (which automatically changes). They are fairly bright but in daytime could be a little better.

### 1/5 — Time change with sign

*2024-03-13, version 2.1*

Worked great until recent time change. Now I can update my sign with the app to correct it to the time change.

### 1/5 — GLI 1050B

*2024-02-07, version 2.1*

Great sign,however we can’t connect to it!!!

## Version history (last 5 releases)

### 4.0.5 — 2026-06-12

What's new in 4.0.5:
• Saves now auto-retry if Bluetooth disconnects mid-write — fixes the "disconnected before response" warning some customers saw.
• Pairing waits up to 35 seconds (was 25) before timing out, so slower signs have more headroom; "Pair anyway" still works if the handshake stalls.
• Cleaner sign-up flow when our server is still finishing up your account — clearer guidance instead of a misleading error.

### 4.0.4 — 2026-06-10

What's new in 4.0.4:
• Fixed a "Network error: The request timed out" that could appear on sign-up and sign-in for accounts that take longer than usual to provision on the server. The app now waits up to 60s for these calls (was 15s); everything else stays snappy.

### 4.0.1 — 2026-06-04

Maintenance update fixing two issues reported by customers in 4.0.0:

• Some account passwords weren't being accepted on the sign-in screen — fixed.

• Pairing a sign occasionally got stuck on "confirming the handshake". Added a longer timeout, clearer error messages, and a new "Pair anyway" option so you can pair the sign and adjust settings if the initial connection takes too long.

Thanks for the bug reports!

### 4.0.0 — 2026-05-31

A completely rebuilt GLI OPEN Sign app — faster, more reliable, and easier to use.
• Brand-new design for quicker pairing and control of your LED OPEN sign
• Use it without an account — pair and control your sign right away, no sign-up required
• Faster, more reliable Bluetooth connection and reconnection
• Refined controls for colors, effects, on/off times, and business hours
• Stability and performance improvements throughout

### 2.9.1 — 2025-04-14

Fixed issue with the all supported displays!
