What errata is available between CYBT-483062-02 and CYBT-483039-02?

CYBT-483039-02 appears to be end-of-life or at least NRND.

Recommended replacement appears to be CYBT-483062-02

Is CYBT-483056-02 also being promoted.

Hi, we're doing final verification for a new product design using the CYBLE-222014-01.

I have found the intentional and unintentional radiator test reports for this device here (https://community.cypress.com/t5/Knowledge-Base-Articles/RF-Regulatory-Certifications-for-CYBLE-222005-00-and-CYBLE/ta-p/253142) but the intentional radiator report seems to be missing some tests. Test report 1622078R-RF-US-P06V02 contains:

- 15.247 (b) Maximum peak power output
- 15.247 (d) Emission on band edge
- 15.209 Radiated emissions limits (spurious emissions)

However to comply with the rules my understanding is that the following tests are also needed:
- 15.247 (a) 6dB Bandwidth
- 15.247 (e) Power spectral density

Am I incorrect in my understanding that these additional two tests are required to pass FCC? Is there any reason why these tests have not been performed?

Thanks

Hi,

We have integrated CYW89820BWMLGT module with imx6ul processor and have flashed firmware.bin and minidriver.bin firmware to this chipset. We are trying to test data transfer  using hcitool commands. 

By executing "hcitool scan" command nearby bluetooth device will get detected but we are not able to pair and connect it. Can you please suggest us any tool which will help us for testing data transfer. 

Regards,

Hi, I'm looking for an electronic schematic or an application note for an infra-red remote control interface between two slot-cars and their hand controllers. It can be bluetooth, infra-red, 433MHz, or RF. It must be proporcionally linear, not simply on/off. The two hand controllers must be fully independent, operating in two different frequencies or channels.

Hi Cypress.

I have some question.

How many Cypress BLE Mesh actually connection of thing?

And can you provide any refer report or test data?

Best Regard.

thank you.

Having already worked with the TI launchpads, I expected to find a thorough several-hundred page technical reference on how the MCU in the CYBLE-013025 really works, e.g. how the devices are memory mapped into the address space, the exception model, ... . Sadly, all I could find is a brief datasheet about the module which then states that the actual silicon is a CYW20737. I couldn't find any technical reference for that MCU either! Curiously, documents in sufficient detail seem to be available for the PSoC line of chips, which makes me believe that there must also be some technical reference for the CYW20737! 

Hence, my question(s):

1. Where can I find the technical reference for the CYW20737?
2. If no such documents exist, how is one supposed to find out about all the intricacies of the MCU?

We are using the CYW20721B2 and looking to fine tune our carrier frequency.   I heard this is done, by Cypress for this part?

I may not be asking this correctly.

Other parts we use, we can set registers to select small capacitor value increments to set the carrier frequency.  Not sure with this part how that is done.

Thank you,

George
