PSoC™ 4 Forum Discussions

Hi,

I am designing a very low power Bluetooth mouse (possibly as small as 10mah battery) and am trying to find out the typical time taken I might expect between a wakeup from hibernate or stop mode to initiating mouse movement, is there much difference between a wakeup from either mode.

If anyone has links to studies on this vs advertising intervals and power that would be great!

Also what happens between when the peripheral fails to respond within the given latency but before Connection supervision timeout? As in, is there any advantage to increasing the Connection supervision timeout beyond the amount of time it takes for the slave latency to naturally expire? I'm not sure what really happens in this period.

Also as a word of advice to cypress, there should be more information on these parameters being new to Bluetooth it took me a while to find these parameters as it was obvious they existed but I did not know initially what to search for as it can be hard to find answers without an initial keyword, aka. latency which is a somewhat misleading name in itself.

Also can the peripheral suggest scanning intervals for the host?

Best regards,

Rob

Hello,

I want to develop a BLE-Device using PSoC 4200 BLE, which sends an ADC-Signal(uint16) and 8 Button-Signals(Digital Input) from Server to Client.

That means, there is an external analog signal input for ADC, and 8 external digital inputs as well.

Could anyone please tell me, are there any suitable examples or definitions of GATT Profiles in the documentations of Cypress?

How can I define the Custom Service?

Thanks!

Hi Team,

Please let me know about the following PCB layout design regarding capsense for PSoC4200.

For series resistance of capsense pins, in the design guide, It is arranged within 10mm of the PSoC pin, and individual chip resistors are used.

Now, we are considering this resistance with the resistor array(Panasonic EXB28V, etc.).

At that time, it is assumed that the parasitic capacitance between the wiring patterns affects by using a resistor array.

Please let me know the design rules on capsense wiring patterns and the recommendations, prohibitions and design materials for making resistor array from series resistance.

Thanks and regards,

Hello, I am using the chip# CY8C4245LQI-483 for our cap sense lighting applications, I have 10 segments and using as linear slider and using Auto (Smart sense),The problem is 9 and 10th segments are too sensitive since its very close to MCU, Is there any way to reduce the sensitivity in Auto mode? If i reduce the sensitivity to 2 it reduces the sensitivity for all sensors

Hi,

How do I get the RSSI of a peered device? Say I'm connected to a peripheral and want to know the RSSI from the Central.

Also whats wrong with this function CyBle_GetRssi(), I'm trying to output an RSSI but gives a postive value and a dBm value lower than -85 e.g. -120, when the documentation say it will only output a dBm range of -5 to -85 dBm, and this is true though for using scanReport->rssi.

Im printing it using:

printf("RSSI: %d", CyBle_GetRssi());

Hi, I'm working on an implementation of Max30100 sensor with my PSOC 4 BLE kit. As mentioned in the datasheet I am getting 4 bytes of data. First two bytes represent IR values, while the next two represent Red values. But I am unable to understand which one is for AC level and which is for DC?

Hello all,i am very much new to to this world ,i just got CY8CKIT-043 prototyping kit and read most of the manuals ,i need to learn coding for that can anyone of you please guide me for it

Hi,

We are prototyping a new instrument which requires APP control via bluetooth or WIFI communication.

There will be no router or network to link up to as users will likely be either outside or in industrial environments.

We would like to achieve a range of atleast 40m depending on capabilities.

I suspect the phone APP will be the limiting factor but I appreciate your help in the best way to get maximum range for APP control of the device.

I don't know weather to use a pcb chip and connect an external gain antenna to it, and if so can we use BLE as we have already begun designing around it.

Any reccomended chips would be great to, currently we designed around the CYBLE-222014-01 which was a mistake as it doesnt have possibility to connect an antenna, however could we use something similar in size etc? would make my life easier.

thanks
