Hi, i have a problem with this API function, when i want to disconnect from the device, (The device ir not connectected yet, i apply this function into: CYBLE_EVT_GAPC_SCAN_START_STOP. 

Later i launch SCAN API function, but i cant connect to other devices, it seem that the BT turn OFF, but BLE State is Scanning....i dont understand why.

Thanks for all

Is there some way to scan/adv while currently connected in central and peripheral mode (respectively).  Perhaps there's some way of "pausing" the connection?

Hello! I want to include service data in advertisement packet. So far I have made it so i can actually see that field changing in CySmart App, but when I try to program Android app to read that field something something goes wrong.

So at the attachment you can see the setup for BLE. In the field data I have written in "00" because otherwise I don't have an index for that field. So in the code I use these three lines to update that field:

 <code> 

#define advPayload                                  (cyBle_discoveryModeInfo.advData->advData)

advPayload[29u] = 0x01;

CyBle_GapUpdateAdvData(cyBle_discoveryModeInfo.advData, cyBle_discoveryModeInfo.scanRspData);

 </code> 

Through CySmart app i can see the changes (I have to stop scan and then start it again). But when I try to write code for android to read that data with these lines:

 <code> 
public static final ParcelUuid THERM_SERVICE = ParcelUuid.fromString("00000000-0000-1000-8000-00805F9B34FB");

public TemperatureBeacon(ScanRecord record, String deviceAddress, int rssi) {

mSignal = rssi;

mAddress = deviceAddress;

mName = record.getDeviceName();

byte[] data = record.getServiceData(THERM_SERVICE);

if (data != null) { mCurrentTemp = data[0]; }

else {

mCurrentTemp = 123; } }

 </code> 

The function just returns NULL, like when no data with such uuid is found. Everything else like address and name is acquired properly. I am using the same parcel uuid for the scan filter and that works fine. So I don't understand what is the problem. Have I set up BLE component wrong?

Hi,

I'm trying to determine exactly when advertisement packets are transmitted. In the Register Technical Reference Manual I found the ADV_TX_INTR bit within BLE_BLELL_ADV_INTR, but it doesn't seem to be working. I've set the ADV_TX_EN bit within BLE_BLELL_ADV_CONFIG. Has anyone else gotten this to work?

Thanks,

Tom

Hello,

I am trying to send the battery level in the advertisement packet. I am using the CY8CKIT-042-BLE. I used the constant broadcaster sample application provided by Cypress and tried to modify it. I used the Timer to decrement the value of the battery as showed in the video lectures. I am able to put custom data in the advertisement packet, but not real time data. Can any one help me?

Hi I am brand new to PSOC and I have some questions

1) My understanding is that you design your hardware on a pioneer board (I have the 042 BLE) and if you create a solid device virtually, then you buy the hardware from cypress to make a prototype?

2) I am not great with programming C. I have watched several videos including the PSoC 101BLE series and it seems like a nightmare to me. Is it still possible to learn to code firmwares to create my device? or should I move on to a different project?

3)My project is on making capacitive buttons out of conductive materials of my choice. I am then going to use that information to control something on the computer or a MIDI instrument. Can this be done with PSoC 4?

Thank you for answering in advance. You'll be saving a newbie developer's life.

Hello,

I want to send string from char array using BLE
I add custom service in Profiles (BLE configuration),
What should I do next?
