PSoC™ 4 Forum Discussions

Team Cypress,

I have "CY8C4248BZI-L489ES" parts here. 

    
• guess that ES means engineering samples
    
• date-code: 1549
   

Can I use these for prototypes or are there any known anomalies that we should be aware of?

Hi,

in our application we have designed an electronic board driven by a PSoC4 (CY8C4247LQI-BL483).

We did the software on the CYC8Kit-042 BLE, which allows programming directly from the PC through the on-board PSoC5 microcontroller.

However, is that possible to programm our own PSoC4 using this kit ? I mean, if SWDIO, SWCLK, RST, GND and VDD from the kit and from our own board are wired (and without any PSoC4 board plugged on the pioneer kit of course) does it work ? Or should we afford the MiniProg3 kit ?

Thank you in advance !

I tried to measure the power consumption of CY8C4247LQI-BL483 device while it is in DeepSleep mode. I followed the instruction in "Project # 27: PSoC 4 BLE - Power Consumption Optimization" by measuring current across the jumper J15. The main() function consists of four lines of code as follows:

CySysClkIloStop();
CySysClkEcoStop();
CySysPmDeepSleep();
while(1);

The current across the jumper J15 shows around 1mA. But when I took the device out of the development kit and feed 3V directly to the device via VDDD and GND and measured the power consumption (between 3V source and VDDD), I got around 3uA as expected. I'm not sure what I did wrong when I try to measure the power consumption from the jumper J15.

I have the PSoC 4 BLE Pioneer kit and have supplemented the ADC example code with authenticated encryption BLE code. My peripheral device is called "Shelf sensor" However, I don't think I have done this correctly because after running CySmart on multiple Android devices, the "Shelf Sensor" only appears on the Nexus 9 and not the two phones. Other PSoC examples show up in CySmart on all three Android devices. So something I did makes the PSoC only appear on the Nexus 9. What could I have done to cause this problem?

I do have pairing enabled, but not the private addresses. The peripheral always has the same address. I did not start from the "Privacy" example. 

Hi, I am using the PRoC eval module (black PCB) and I'm trying to figure out how to change the name of the device through a mobile app.  Is there a selection in Creator's schematic editor to allow for this?  Or, do I need to write custom code?

Hello,

I am developing application on PROC4 BLE as a central device. My side is client side.After passing address of peer device to which my device wants to connect to the Gapc_connectdevice function it gives api result :CYBLE_ERROR_INVALID_STATE which is explained as : On calling this API not in Disconnected state.

I have called Cyble_gapcstopscan() and  CyBle_GapDisconnect(cyBle_connHandle.bdHandle) before calling Gapc_connectdevice () function.

But it still shows "not in Disconnected state" result and hence CYBLE_EVT_GAP_DEVICE_CONNECTED is also not generating.What is exact meaning of this api result?

What are the possible faults?

Thanks. 

hi.

i have to work on 3.3 V in my project but i gives 5 V to psoc-4. is that any configuration in psoc-4 which takes 5V and work on 3.3V ???
