Dear Infineon team,
We are going to get the SIG certification using the 89820.
But current SIG certification needs to use the TCRL 2019-2.
We've got almost part of the evidence for the Stack QDID. But certification company request the evidence of below item.
Read Characteristic Descriptors - by client
We've referenced the QDID #115853.
Could you let me know how to get the evidence of this item?
I've recently been experimenting with flashing firmware to a CYBT-413055-02 with the "WsOtaUpgrade" tool built into
I had no issues flashing a modified BLE_Beacon example to a brand new CYBT-413055-02 evaluation board over the air.
However, when attempting to flash the same firmware to a brand new CYBT-413055 module on a different PCB, the WsOtaUpgrade tool fails and states : "This device may not support OTA FW upgrade. Please select another device." This module is detected as "mtk_dut_413055" on a BLE scanner app.
Does anybody know what might be preventing me from flashing new CYBT-413055 modules OTA? Any insight would be greatly appreciated
I was hoping to create an airpods like headset using 2 eval boards (CYW920721B2EVK-02).
I see the bluetooth headset example projects, but these seem be just for 1 single device/headset. Has anyone had success using 2 devices, acting as a headset when connected to a phone, similar to the functionality of all the wireless earbuds on the market today?Show Less
I was looking to create a pair of wireless earbuds using 2 CYW 920721B2EVK-02 eval boards.
Upon answering a phone call from a users phone, both earbuds would have the phone call audio streaming at the same time.
I have seen in press releases that this hardware is made for such an application, however I am having trouble finding any documents or examples on how to implement "WASS" on the eval boards.
Has this feature been implemented yet into the 20721 hardware as of yet?
Any help would be appreciated.
1.20706 是否支持BLE5.0或以上？如果支持 SDK是否需要升级？我们期望使用5.0的2Mbps特性获得蓝牙传输速度的提升，目前我只能确认当前SDK是支持长MTU。
As I know, MBT 2.2 and BTSDK 2.8.x supports for BT Core 5.0. But our customer wants to receive BT Core 5.2 with CYW20706 for BT SIG certification because it's listed as BT 5.2 in BT SIG.
When I check the air log using MBT 2.2 and BTSDK 2.8.x, it's shown as BT Core 5.0. Please see the attached air log.
Q) To receive BT SIG certification with BT Core 5.2, what should we do?
We are using CYW89820BWMLGT chipset in our i.Mx6 based custom board. As there is no firmware available in the chipset we are not able to test the chipset functionality in our board.
Please let us know is it required to program the module first. If yes , Please clarify us that is it through HCI UART protocol commands. If No, Please let us know the commands and document to refer.
Also if programming is necessary what is the address to which the firmware is to be programmed using the commands.
Dear Cypress expert,
I wonder that how to measure RF Performance (RF Test) of CYW20819, CYW20721 and CYW20719 about Bluetooth Classic and BLE.
CYW20819, CYW20721 and CYW20719 are being reviewed on Cypress website.
And I want to measure RF Performance of Classic BT and BLE by purchasing CYW20819 or CYW20721 or CYW20719 Evaluation Board in Window 10 OS. (included Basic Rate, Enhanced Data Rate, BLE)
1. Current Review
① I have checked the contents about CYW20819 in below document.
- CYW920819EVB-02 Evaluation Kit User Guide.pdf
- CYW920819EVB-02 Evaluation Kit Quick Start Guide.pdf
② And I installed below software (= Compiler).
③ However, it can't find Stack (Software) that can measure RF Performance.
④ And it is confirmed that there is no guide document to measure RF performance.
① Isn't the Guide & Stack (Software) that can measure RF Performance provided for free on Cypress Web?
② If software and documentation exist, please provide a link.
③ Finally, if I purchase CYW20819 or CYW20721 or CYW20719 Evaluation Board, can I get a Guide & Stack (Software) to measure RF Performance?
④ In case, even Classic Bluetooth (included Basic Rate, Enhanced Data Rate), please let me know if there is
any product that is open for RF Performance Measurement.
please answer about my question.
What would be the easiest method of combining the audio sink example with the hello sensor example on CYW920706WCDEVAL kit
Audio_Sink is bluetooth classic, while BLE_Hello_Sensor is BLE
None of these examples have a bluetooth configurator file (.cybt) in their repositoriesShow Less
（1）相比于CYBT-343026-01， CYBLE-0130xx-00是否出厂就带透传固件的，买来可以直接用的？以及它的传输速率情况如何？ CYBT-343026-01， SPP profile和电脑的透传速率，上行65KBps，下行35KBps。BLE的速率大概在20KBps左右。
