CHATFIELD
ChatField provides model-specific FCC evidence for the J25 phone-paired LoRa mesh communication device.
The evidence identifies FCC ID 2BVP9-J25, the named grantee, the authorized frequency ranges and the supporting test reports used for the stated scopes.
Procurement teams should match every document to model J25, the proposed radio configuration, the destination market and the exact product supplied under the quotation.
J25 · FCC EVIDENCE IDENTITY
Begin with the identifiers that must match.
These identifiers connect the product, grantee, authorization grants and supporting reports. If the model or supplied configuration changes, the applicability of the evidence must be reviewed again.

FCC-TESTED RADIO SCOPE
Read the authorized radio layer in buyer language.
Bluetooth Low Energy links the smartphone to its paired J25. LoRa links participating J25 terminals inside the configured local team network. The FCC evidence covers the radio scopes below; it does not certify the performance of every app workflow or field deployment.

SUPPORTING J25 TEST MATERIAL
Keep the grant and its supporting reports together.
A grant is the authorization record. The test reports provide the detailed methods, conditions and results for their stated scopes. Buyers should retain the report number rather than describing every file only as a “certificate.”

Each document answers a different approval question.
- 01Product identityDoes the offered device and quotation identify ChatField J25?
- 02FCC IDDo the label, grants and reports identify 2BVP9-J25?
- 03Authorization grantWhich equipment class, rule part, frequency range and output are listed?
- 04Supporting reportWhich report number, test scope, version and result support the review?
- 05Commercial matchDoes the supplied radio, battery, accessory and app configuration match the approved quotation?
- 06Destination marketIs FCC evidence the correct regulatory basis for the country receiving the product?
WHAT FCC EVIDENCE DOES — AND DOES NOT — PROVE
Prevent the two most common procurement mistakes.
What the current public evidence supports
- FCC ID and grantee identity for model J25
- DTS and DCD TCB Grant of Equipment Authorization records
- FCC-tested LoRa and Bluetooth Low Energy radio values
- Model-specific WPT and EMF supporting reports
What must be checked separately
- Battery transport evidence for the exact supplied battery configuration
- Requirements for a destination market outside the United States
- Hazardous-location, marine, life-safety or other sector-specific approvals
- Operating range, enclosure, accessories and final commercial configuration
BATTERY TRANSPORT DOCUMENT CONTROL
UN38.3 and MSDS files must match the battery actually supplied.
ChatField has battery-related source files under review, but they are not posted as universal J25 evidence. A cell-level report cannot be represented as supporting every finished-product battery configuration until the bill of materials and supplied battery relationship are confirmed.
Before release, ChatField confirms:
- Cell and battery model shown in the source report
- Voltage, capacity and watt-hour rating
- Manufacturer and tested sample identity
- Relationship to the finished J25 configuration
- Revision required for the shipment and destination
DESTINATION-MARKET CONTROL
FCC evidence is not a worldwide market approval.
The public documents on this page support U.S. review. For another country, ChatField must confirm the permitted frequency configuration, marking, importer or responsible-party requirements and the exact documents needed before shipment.
Use the J25 FCC evidence set
Match FCC ID 2BVP9-J25, the grant scope, supporting reports and supplied configuration.
Run a separate market review
Do not use the U.S. 903–927.5 MHz FCC configuration as automatic proof of local conformity or permitted operation.
Confirm before quotation approval
Share the country, intended use, quantity and required document list so the correct configuration can be reviewed.
PROCUREMENT DOCUMENT REQUEST
Request evidence against the actual J25 order.
Send the destination country, quotation reference, product quantity, intended use and requested document list. ChatField will separate public FCC material from configuration-controlled and market-controlled files.
J25 compliance questions from procurement teams
What is the FCC ID for ChatField J25?
The FCC ID shown in the current J25 grants and supporting reports is 2BVP9-J25. The named grantee is Jingxi Box (Shenzhen) Intelligent Technology Co., Ltd.
What is the difference between an FCC grant and a test report?
The TCB Grant of Equipment Authorization records the authorized equipment class, rule scope and listed radio values. A supporting test report contains detailed test methods, conditions and results for its stated scope.
Which LoRa values are supported by the J25 FCC files?
The J25 LoRa report identifies 903–927.5 MHz, CSS modulation and 16 channels. The DTS grant lists the same frequency range and 0.01057 W conducted output.
Which Bluetooth values are supported by the J25 FCC files?
The Bluetooth Low Energy report identifies 2402–2480 MHz, GFSK modulation and 40 channels. The DTS grant lists the same frequency range and 0.0008 W conducted output.
Why is the battery transport certificate not posted publicly?
UN38.3 and MSDS evidence must match the exact battery supplied with the finished J25. ChatField will release a configuration-matched document set after the battery model, capacity, manufacturer and finished-product relationship are verified.
Does FCC authorization approve J25 for every country?
No. FCC evidence supports U.S. review. Other destinations require a separate check of permitted frequencies, conformity requirements, responsible parties, markings and supporting documents.
