PSoC™ 4 Forum Discussions

I am working on trying to get a mesh network up and going to control some simple led strips rather the led lights in the smart mesh demo that was given for CES 2016. 

Video of the smart mesh demo

https://www.youtube.com/watch?v=g6O9MW3pKRM

I started with using the demo projects from the cypress git hub for the smart mesh networks. Both the flooding and directed flooding, seem to have about a three second turn around from when I can press the button for a color change to when the next color change can happens. I have tried to reduce this turn around by adjusting not only the watchdog timer that is being used as the counter,and also the central state span. When I reduce these down though, the number of packets drops increases greatly and I can never get to what seems like what is working for the mesh network in the video above. 

Currently I only have two nodes in the mesh network, so I don't think that it could be an issue with the number of nodes.

I am wondering if someone can give me some advice on how to speed up the network to be able to have the response time like in the demo video?

Dear community, 

we are working on a product which would greatly benefit from Bluetooth Mesh Networks. Multiple devices would all be connected to one phone. The devices should be able to repeatedly blink a light at exactly the same time. 

With the new Bluetooth 5 spec adopted yesterday, and Cypress having a Mesh Network solution already for Bluetooth 4.2 compatible chips, I hope I can find an answer to this interesting question:

Using mesh networks, do you think a very accurate synchronization of all the devices in the network is conceivable?
Would it be possible to compensate for all the individual delays that occur between the devices?

Back in June of this year I bought a Cylakit e-02 and installed all the software required to flash the beacon. At that time I was trying to get the kit to work as an eddystone beacon. I was provided a file called Simple_Eddystone_0.zip, which worked perfectly. Last week I bought 15 more beacons and was going to flash them with new URLs but the PSoC creator software is no longer working. I tried uninstalling. I tried re-installing. I tried everything I can think of. I am getting an error regarding the BLE component, but I do not know what to do about it or why it is appearing. Here is some info about the error:

sdb.M0033: The instance 'BLE', of component BLE_v3_30, contains an error. Unable to load symbol 'C:\Program Files (x86)\Cypress\PSoC Creator\4.0\PSoC Creator\psoc\content\cycomponentlibraryupdates\CyComponentLibraryUpdates.cylib\BLE_v3_30\BLE_v3_30.cysym' for component 'BLE_v3_30'. Parameter is not valid.

Parameters: The most common kind of error in a component instance is that its configuration is incorrect, invalid, or unsupported. For example, the component may require a clock frequency that is not available given the current system clock configuration. Dependencies: If the component cannot be found try looking at the project's dependencies. Make sure that the "Component" depenedencies are correct.

I downloaded the software from the web page for the Cylakit.e-02. I tried the .iso file as well as the complete software dowload. They are all giving the same error.

Any help would be greatly appreciated.

PS I just reloaded all the software and the first error I see is this:

Symbol file for instance "BLE" of component "BLE_v3_30" not found. Can't edit current instance. Check your search path.

The files seems to be exactly where the program is looking for it.

I watched the video on adding a battery service and I completed the exercise and code.

Now I've added a custom service and want to write data to it.

If the battery service is accessed like this:              locHandleValuePair.attrHandle = cyBle_bass[0].batteryLevelHandle;

I see the syntax for accessing my custom service is cyBle_custom. But that variable does not contain the handle for the service i added. Why?

Is there an example simple custom BLE with code I can look at?

PSoC creator 4.1, cyc8ki-042-BLE pioneer board, 222014 plugged in. USB connected to PC. teraterm running connected to the provided com port.

Create new project for the above.

in main, add printf("hello world\n");

build, debug, run. program hangs up (printf never returns). no output on teraterm.

Whiskey Tango Foxtrot?

Hi all,

I am having some problems with using the ADC and outputting the result over I2C using CY8CKIT-042-BLE and would very much appreciate your help please!

I am trying to send 12-bit ADC output over I2C and have set up a 6-resistor potential divider to help me understand the different generated output compared to the actual voltage levels.

I am using:

Vref = VDDA/2

Unsigned differential mode

Vneg is externally set to VDDA/2

When I use the alternative resolution in the ADC and set this to 8-bit I get the output that I would expect as Vpos is changed from 0 to VDDA (3.3V), that is 0x00-0xFF.

However, when I change it back to 12-bit I get the following output:

3.3V     0x00FF

2.75V     0x006C

2.2V     0x00C0

1.65V     0x0016

1.1V     0x0069

0.55V     0x00C3

0V    0x0011

To me, it looks like the most significant 4-bits are missing.

In my code I am using the bit-shifting code to access the two bytes:

i2cbuf[1] = (adcVal >> 😎 & 0xFF; // First byte

i2cbuf[2] = adcVal & 0xFF; // Second byte

As a test, if I only bit-shift 4 bits then I output a copy of bits 4-7 which makes sense.

I am most likely making a simple mistake so I would be very grateful if someone could suggest reasons for this error and/or things for me to clarify/check to get to the bottom of this.

Many thanks,

Rich
