A continuous glucose monitoring system may include a sensor, applicator, transmitter, receiver and mobile app. These parts can be specific to one model or generation, even when they share the same brand name. This CGM sensor and transmitter compatibility checklist explains what to verify before ordering a complete system or replacement component.
This guide provides general product information only. Always follow the current instructions for the exact CGM system and obtain qualified professional guidance where appropriate.
Identify Every Part of the CGM System
Before comparing listings, write down the complete product name and model number for every component you already have. Do not rely only on color, packaging design or a shortened marketplace title.
- Sensor model and generation
- Applicator type
- Transmitter model, if separate
- Receiver model, if used
- Official mobile app name and version requirements
- Compatible phone and operating system
- Any required account, activation code or regional service
Sensor Generation Must Match the System
A newer sensor generation is not automatically backward-compatible with an older transmitter, receiver or app. Manufacturers may change the physical connection, communication protocol, activation process or wear period between generations.
Ask the seller to confirm the exact compatible models in writing and compare that information with the manufacturer documentation. If a listing uses terms such as “new version” or “second generation,” request the full model or reference number.
Separate Transmitter or Integrated Transmitter?
Some CGM sensors use a reusable or limited-life transmitter attached to the sensor, while other systems integrate communication hardware into each disposable sensor. This difference affects what must be ordered and replaced.
| System design | Questions to verify |
|---|---|
| Separate transmitter | Which sensor generation fits it, how long it is intended to operate, and whether pairing or charging is required? |
| Integrated transmitter | Is communication hardware included with every sensor, and what app or receiver activates it? |
| Dedicated receiver | Does the receiver support this exact sensor and software generation? |
| Phone-only display | Is the official app available and compatible with the intended phone and region? |
Check the Package Contents Carefully
A product photo may show the complete system while the price applies only to one component. Use the written package-content list as the primary reference.
- Number of sensors included
- Whether applicators are included with each sensor
- Whether a transmitter is included or sold separately
- Whether a receiver is included
- Charging cable or accessories included
- Adhesive patches or preparation items included
- Manual language and support information
Review the package information for the AiDEX Continuous Glucose Monitoring System – Second Generation and ask for clarification before ordering if photos and written contents differ.
Verify the Official App and Phone
Bluetooth capability alone does not confirm compatibility. Check the official app name, developer, regional availability, supported phone models and operating-system versions. Confirm whether account registration, internet access or a particular phone permission is required.

Receiver and App Use May Differ
Some systems allow both a receiver and phone app, while others allow only one display device or require a particular pairing order. Verify whether simultaneous use is supported and what happens when switching phones, replacing a receiver or reinstalling the app.
Do not reset or unpair a working component until you understand whether activation codes, stored records or an active sensor session could be affected.
Regional Versions and Account Availability
A CGM component sold in one country may use a different app, unit, language, model suffix or support process from a product sold elsewhere. Before cross-border purchase, check:
- intended sales region;
- official app availability in the destination app store;
- measurement units and language options;
- account and phone-number requirements;
- local replacement-component availability;
- manufacturer support and warranty region;
- applicable import and product requirements.
Wear Period and Replacement Schedule
Confirm the manufacturer-stated wear period for the exact sensor. Do not infer it from another generation. If a separate transmitter has its own service life, note its activation date and replacement guidance independently.
An adhesive overpatch cannot extend the approved sensor wear period. For daily-wear preparation, read the CGM Sensor Adhesion and Daily Wear Checklist.
Storage and Shipping Compatibility
Check the permitted storage temperature, humidity, expiration information and packaging requirements. Cross-border transit can be longer than domestic delivery, so review the product’s storage limits and the seller’s shipping method before purchasing.
- Confirm expiration or use-by information where available.
- Do not use packaging that arrives opened or damaged.
- Follow the stated acclimation or preparation instructions.
- Do not refrigerate or freeze a sensor unless explicitly directed.
- Keep model and lot information for support questions.
Before-Ordering Compatibility Table
| Component | Information to match |
|---|---|
| Sensor | Full model, generation, reference number and wear period |
| Transmitter | Compatible sensor generation, service life and activation method |
| Receiver | Model, software compatibility and pairing limitations |
| Mobile app | Official app, region, phone and operating-system support |
| Account | Registration, country, internet and data requirements |
| Accessories | Model-specific applicator, charger, patch or protective cover |
Warning Signs in a Product Listing
- No exact model or generation is stated.
- Photos show several different versions.
- The transmitter or receiver inclusion is unclear.
- The required app is not identified.
- Claims of “universal compatibility” lack manufacturer documentation.
- Wear period or package quantity differs across sections.
- Unverified regulatory or approval claims are used.
- Storage, expiration or return information is missing.
Frequently Asked Questions
Can I use a newer CGM sensor with an older transmitter?
Not unless the manufacturer explicitly lists the exact models and generations as compatible.
Does every CGM sensor need a separate transmitter?
No. Some systems use a separate transmitter, while others integrate communication hardware into the sensor. Check the exact model and package contents.
Can I use any Bluetooth phone with a CGM?
No. The official app, phone model, operating system and regional availability must all be compatible.
Can a receiver and phone app work at the same time?
This varies by system. Confirm supported display combinations and pairing order in the manufacturer instructions.
Are CGM components interchangeable within the same brand?
Not necessarily. Different generations may use different physical, software and activation requirements.
What if the received component has a different model number?
Do not activate or use it until compatibility is confirmed. Preserve the packaging and contact the seller using the stated return process.
