b. Charger

c. RFID cards (Quantity: 3)

Modification to Database

There is a need to include another table to map the RFID code with the product identifier (pr_id).

This table was not included in the earlier design; however we will need to include it now.

Table Name: bltoo_ref

Table Template: RFID and product mapping

Purpose: The unique RFID codes need to be mapped with the unique product identifiers (pr_id). This

will enable the app to correctly identify the product and show its details on the screen.

Column count: 3

Insert: Yes

Update: Yes

Delete: Yes

Upload: No

Sample:

shop_id bl_id pr_id

ABC123 33908 10000019

ABC123 42129 10000071

ABC123 42537 10000004

(Use this table along with the values for implementation. The bl_ids are the RFID codes of the 3 RFID

cards included in the package.)

Flow for Identifying product

Product placed on the antenna

bl_id passed over Bluetooth

Use bltoo_ref table to get the

pr_id

Use pr_id to reference other tables like pdt_map, attr_value,

price_data, rating_data,p_c_data and rating_data to get

product details

Modification to the Interrupt Messages

The format remains unchanged but now we will ignore the first field. We should use the next two

fields to identify the interrupt type. NO product is signified by Zero value i.e. 0. If either of the 2

fields holds a Zero value implies its Interrupt 1. If none of the fields hold Zero value then it is

Interrupt 2 and if both fields hold Zero value then its Interrupt 3.

Message format:

<variable 1>, <variable 2>, <variable 3>

Variable values:

<ignore this field>, <antenna “A” data>, <antenna “B” data>

Antenna “A” data or Antenna “B” data implies the bl_id value.

Interrupt 1 (No products -> 1 product) – one product is placed on either of the stands

Example of interrupt 1message:

1, 33908,0 (when product is kept on Antenna “A”)

or

1, 0, 42129 (when product is kept on Antenna “B”)

Interrupt 2 (1 product -> 2 products) – Two products are placed for comparison

Example of interrupt message:

1, 33908, 42129

Interrupt 3 (2 products or 1 product -> No product)

Example of interrupt message: 0,0,0

For checking the Bluetooth module you can use SENA Bterm Bluetooth Terminal app for Android. It

is available in the Google Play store.
