PSoC™ 4 Forum Discussions

I have a CY5677 CYSMART BLE 4.2 USB Dongle and a CYBLE-214009-00 evaluation board.

I am trying to use the USB dongle as a uart-ble bridge to communicate with the CYBLE-214009 through a serial terminal. When I type a character in the serial terminal, the usb dongle should transmit that character to the cyble-214009 and the cyble-214009 should in turn send continuous sensor data for about two minutes.

Would it be possible to use the 'UART to BLE bridge peripheral' project to program the usb dongle, and edit the 'UART to BLE bridge central' project to program the CYBLE-214009 to send sensor data over BLE through UART? What changes would I need to make?

I'm starting to doubt whether this is even possible. I'd be grateful if someone could tell me if I'm wasting my time:

i have created a custom PCB using a PSoC4 BLE module.  I plan to have some number of these same units within the BLE operating distance of a similar number of iPads.  I want to be able to pair/bond/connect a given iPad to one and only one of these peripheral units and each unit be able to connect to only the one iPad.

The ipad will be running an app specifically designed for this and will include a provision to specify which peripheral unit to connect to.

I've tried using different local names in each peripheral which works fine when only one peripheral is advertising but when two or more are advertising the iPad seems to not care what the local names are and will sometimes connect to the one with a different local name. 

Is this a place to be using PSoC's public address or what should I do (if it really is possible to do this)?

Thanks,

I remember reading that setting up a PSoC 4 BLE as a peripheral for an iPad (iOS device) needs certain parameter values as required by Apple, but I can't find this information.  Can someone please direct me to it?

Hello,

what is the best approach to manage a PSoC Creator projects with source control software like git.  What files can be omitted to keep things neat and clean?

Thanks!

Hello,

I have seen several threads about MTU in android.  Some claiming that the max MTU for android is 23 or so, others claiming it goes up to 512.

I have had some difficulty myself getting to the bottom of this.  In fact, I am able to increase MTU  considerably close to 512, however the reason for it is unclear.

In my android studio project, I have tried to negotiate the MTU in several locations throughout, with no success in changing MTU and increasing overall data transmision.

However, I find when insert negotiateMTU function into the OnConnectionStateChanged function, as soon as the device connects, I am able to change the MTU and get higher MTU and data transmission.

However, When I try to reduce the MTU, for example if I do not want so much data, I am not able to lower or change.

I should say, negotiateMTU funciton is not doing anything more than mBluetoothGatt.requestMtu(mtuVal); in java.

I would appreciate anyone's insight into this for changing MTU rate of the device.  Not sure even if the problem is Psoc Creator Firmware or if this is Android.

Attached are PSOC Creator Firmware and Android Java Class which handles BLE services (search (OnConnectionStateChanged for example)

Hi,

I am looking at using the CYALKIT for a project, standard firmware has demo mode and timer mode. Within my application I want the user to be able to use a switch to change between demo mode and timer mode. Can I change the firmware to use the charge from the 0.1F cap when in demo mode and charge that cap during timer mode?

Thanks
