项目编号 006:BLE Central with Immediate Alert Service

In previous examples we've used the BLE Pioneer Kit as a GAP Peripheral device, that will connect to a mobile phone or the CySmart USB Dongle acting as the GAP Central device.

In today's project, we demonstrate how to use the BLE Pioneer Kit to implement a BLE GAP Central device. This is useful for cases where the end-application does not connect to a mobile phone, but instead to another embedded controller with BLE.

Accordingly, the respective GAP roles are also reversed - the BLE Pioneer Kit now acts as the GATT Client, whereas the CySmart USB Dongle acts as the GATT Server.

The project implements a GAP Central device running the Immediate Alert Service. It can write the Alert Level Characteristic to a Peripheral device. Pressing a button on the kit will cause it to connect to the dongle, and the LED on the kit turns to Blue to indicate a successful connection.

One way to think about this project is that its similar to the example in Project #001: BLE Find Me, but with the roles on kit and the dongle reversed.

Hello,
Thanks for all these projects first off I am very impressed!! Regarding this particular project I was trying to understand how PSoC Creator determines which device is being targeted for programming. I realize the Dongle has a different end PSoC BLE device selected but imagine I had 2 PSOC 4 BLE Kits plugged into a PC. How do I dictate which board is being targeted for being programmed? I have a need to expand on this project with a BLE Peripheral and a Client and would be very useful if there is a means to determine which one is actually being programmed/debugged. Is it possible to have 2 board actively being Debugged?

Regards,
Embedded Masters

Hello,
First off Thanks for all the projects!! Quite impressive in assisting someone getting up and running with these devices. My question is how does the PSoC Creator know which 'target' is being programmed, Dongle or PSOC 4 Pioneer board? I tried to see if there was some sort of Serial port being defined or set somehow in the project settings and did not find anything. I have a need to expand this project for a peripheral & client and would like to have 2 Pioneer kits plugged into a PC and need to be able to distinguish which one is being programmed/debugged. Secondly is it possible to have 2 targets being Debugged at the same time or only 1?

Regards,
Embedded Masters

How many peripherals can a central connect to?
