The Module have a dedicated VREF pad, but I guess it's only for bypass cap use?

If I import a battery monitor example it wastes a pin, example P3.3 that it calls Vref.

What is the difference between VREF and Vref?

I have access to LDO 3.3V voltage, would this help getting around wasting a pin?
​The 0.03Vdrop LDO is for a subsystem, so I do plan to run the BLE directly from li-po battery
and have it turn off the ldo when subsystem is sleeping.

Hello,

I use the device Cy8C4013LQI.

I must disable all components for power saving.
So I followed the instruction to change the debug interface to from SWD to GPIO.

Programming should always be possible.

But after download the firmware I can not connect the device anymore.
I use Segger-Jlink with the newest Firmware and software.

Here I found a similar problem.

There are speaking about the version p, but in the download area only available version j.

So - how can I fix the problem? Now I blocked 3 prototypes.

Hello,

I tried a lot of different things, but nothing works really good.

System-Resourcen
1 digital Input with pullup (used for WakeUp Key)
1 digital Output on 3.2 PWM mode strong drive
Clock 12MHz

If I try the following:

CySysWdtDisable();
PWM.Stop();
CyDelay(50u);
Motor_SetDriveMode(Motor_DM_ALG_HIZ);
Key_PWR_SetDriveMode(Key_PWR_DM_ALG_HIZ);
CySysPmDeepSleep();

still I consume aprox. 670µA on 3.3V

But only if I run this after a fresh Power-On Reset.

If I start the PWM, and run then in the same Power-Off, i come to 1.8mA

How can I save more Power? The Hibernate-Mode don´t exists on this device.
In the Datasheet should be the Power-cosum in DeepSleep 4.5µA - this would be nice.

What must I do, to save the maximum power as possible. I will wakeup on Key-IRQ, I must not keep nothing in Ram - I can reinitialize all again.

Hi all,

Is there any SPI master ( UDB mode ) example codes that illustrates how to use multiple slaves with it ? 

Hello,
I'm wondering if it is possible to modify the timeout interval between sending a Write Request (using CyBle_GattcWriteCharacteristicValue) and getting CYBLE_EVT_TIMEOUT event in case the Write Response is not received. The default timeout seems to be 30 seconds, which is a bit too long for our application. Changing cyBle_connectingTimeout has no effect (it works for connection timeout, though).

We are using CYBLE-022001-00 and BLE component v2.30 in PSoC Creator 3.3 CP2.

Thank you in advance!

With Wearable BLE, the design will pretty much be based around the coin-cell diameter.
​So I recommend next Cypress BLE module will not need ground clearance, as that is hard to find on top of a coin-cell.
