Studio Bluetooth Forum Discussions
Hi, i use the demo board of CYW92070xV3_EVAL for near one month. And it now doesn't work smoothly. It often downloads failed and gives a hint that the CYW20706 was not detected. And i have checked the power supply and the driver, and they are all normal. Only when i reinstall the WICED-Studio-5.0, the demo board can then work. But after several hours,it will come the same question. Can you help to analyse the problem? Thanks.Show Less
BT800, Bluetooth v4.0 Class 1 HCI
The BT800 series of Class 1, USB HCI modules, and packaged USB Dongle, are Laird's first dual-mode Bluetoothv4.0 offerings, bringing support for Classic Bluetooth and Bluetooth Low Energy (BLE) for operating system backed devices.
These modules present a Bluetooth standard HCI interface and have native support for Windows and Linux Bluetooth software stacks. BT800 devices are fully qualified as a Bluetooth Subsystem. This allows designers to integrate their existing pre-approved Bluetooth Host and Profile subsystem stacks to gain a Bluetooth END product approval for their products.
A fully featured, low-cost developer’s kit (DVK-BT800) is available for prototyping, debug and integration testing of the BT800 series modules and further reduces risk and time in development cycles.
- Bluetooth v4.0 - Dual mode
- Classic Bluetooth
- Bluetooth Low Energy
- Compact footprint
- Class 1 output – 8 dBm
- USB, GPIO, I2S & PCM
- Industrial temperature range
- 64k EEPROM support for BLE HID Proxy
- Bluetooth SIG approvals
- FCC, IC, and CE approvals

One of my customers would need a BT Audio Connection to a smart phone, and parallel to a BLE connection to a remote control.
Certified Module preferred. !
I2S interface needed to the host processor.
When will be Modules based on CYW20719 available ?

When I installed WICED 220.127.116.11, there was an error "Not enough free disk space on selected folder location. Selected location has only 1M space available, press OK to select a different location where there is at least 1000 M space available." However, the available space of my selected location is more than 50 G. I always tried the root directory of C disk, this error also happened.
One of my collegue, he successfully installed this SDK, but I don't know there is any difference between his PC with Mine.
Is there something wrong with this SDK or there is some confilct with other software?@Show Less
I've found in datasheet that CYW20706 supports CTS wake up when talking about HCI UART
1. Low-power out-of-band BT_WAKE and HOST_WAKE signaling (datasheet section 1.1)
2. The CYW20706 UART can perform XON/XOFF flow control and includes hardware support for the Serial Line Input Protocol (SLIP).
It can also perform wake-on activity. For example, activity on the RX or CTS inputs can wake the chip from a sleep state (datasheet section 5.3)
Would you please tell how to implement the BT_WAKE or HOST_WAKE via UART?

i want to get the local bd address, and i use the library function (void wiced_bt_dev_read_local_addr(wiced_bt_device_address_t bd_addr)).
I print the bd_addr ,but it is an array of two bytes which are not equal to six in the sample code. I want to know the reason and if i can use the function
to get local bd address.
i have a question about the use of the function that wiced_bt_dev_set_local_name.
There is no sample to use this function. Can you explain more?
The technical documentation indicates that cyw20706 supports full-speed USB, but I did not see any relevant support in the source code.Show Less
Hi, i have a question about setting the tx_power. And i want to adjust the value of the tx_power, but i didn't find what's the function. Can you give me some suggestion? Thanks.Show Less
