Confidential NFC BCA Integration Guide
1. Introduction
Sonim NFC BCA has a NFC chipset based circuitry with a proprietary bus interface designed
for using with the Sonim mobile phones. The NFC BCA has been designed and tested with
phone models having the corresponding bus connector interface only.
The Sonim NFC BCA is primarily targeted for reader mode deployments.
The NFC BCA uses the following pins from the Sonim connector interface –
• I2C (with interrupt)
• Power
In the context of NFC BCA, the user mostly refers to a corporate customer who requires
deploying a NFC based solution for the enterprise wide usage.
It is recommended that before deployment, the user makes a complete integration test run in
order to validate the NFC functionality, compatibility and suitability for deployment.
Mobile phone models such as Sonim XP1301 Core come with the NFC BCA pre-integrated
with the phone. Here, the phone is ready to start integration tests of the phone.
Where the phone does not have the NFC BCA, the user needs to first place order for sample
units. The user must have a compatible Sonim mobile phone with an appropriate firmware
version flashed on the phone or place an order for phones along with the NFC BCA units. If
the phone firmware does not support the NFC BCA function, the user must request for
firmware upgrade while placing an order for the NFC BCA. The users must arrange for NFC
tags by themselves. Sonim does not provide any test tags.
Sonim shall provide the required support by providing the appropriate firmware upgrade and a
simple Java (JSR 257) based NFC test application. The user can install the application on the
phone following the standard Java application installation procedures as mentioned in the
user guide.
In order to connect the NFC BCA, the user must follow the standard instructions of
inserting the battery cover as mentioned in the user guide.
