AIROC™ Bluetooth Forum Discussions
The data sheet for CYBT-353027-02 states that XRES has an internal resistance.
Please tell me this resistance value.
I have an IoT project for a client where I need to connect to a phone as a BLE peripheral. While connected to the phone over BLE, I need to scan for a new connection to a Bluetooth Classic device, connect, and communicate with this device. Do any Cypress dual-mode Bluetooth modules support simultaneous BLE and Bluetooth Classic connections?
Step by step, according to AN91445 (Antenna Design and RF Layout Guidelines),I used HFSS to simulate the S11 parameters of MIFA antenna.The simulation results are very different from those in Figure 17.
The.brd files of MIFA for a FR4 PCB with 1.6-mm thickness are provided in the AN91445.zip file.Even when the PCB thickness (1.0-1.6mm), ground plane area (20 mm × 20 mm to 50 mm × 50 mm, Based Figure25) and L_tip, L_leg length,(Based Table3 )are adjusted as required,Results similar to Figure17 were not obtained (the best S11 data was about -5dB).COuld you provide specific PCB critical values and simulation parameters for the results in Figure17 ?
Now, I can't reset CYW920719Q40EVB-01 by CyBluetool software. What's the problem will be?
I can Build & Download Applications via WICED Studio. Is it causing the board can't be connected with cybluetool after downloading a program by WICED Studio?
What should I do?
I am looking into CYW20704A2.
- What is the difference between CYW20704 and CYW20706. Can you please share link for datasheet/specifications for CYW20704A2.
- For certification related do I need to search as BCM20704 or CYW20704.
- For CYW20704 I am seeing only controller subsystem with QDID 159590 but not Host subsystem. If WICED is the support stack then what is the Host subsystem QDID.
Thanks & Regards
