我们有个项目需要用到蓝牙模块,具体需求是串口接口,至少1对5连接,通讯距离40米以上,功耗尽量低一点8mA以内,BLE5.0以上,请推荐下合适的蓝牙模块,谢谢!
Hi,
We have build a custom board with the CYW20706 but are now running against the problem that we haven't placed an external flash for the pgroam data. Is it possible to store the program data in the onboard ROM instead of the external neccessary flash.
How can we store the program data in the onboard ROM of the CYW 20706 device and what is different when using an external flash instead of the onboard ROM.
With kind regards,
Richard
Show LessHello.
One of my goal is sending data from PUART to rfcomm(SPP).
In my previous project with CSR support bypass mode(PUART -> SPP) but Cypress don't have such features in my Study.
So I'm working on Bypass mode(PUART->SPP) by myself.
My Request.
I know you support thread APIs and Mutex.
But I want to make sure that CYBT-413034 receive data via PUART while SPP is sending at the same time. (multi thread)
Please give me any advice.
Thanks.
Show LessHi,
We would like to connect the CYW20706 to a portofoon taget device and currently have this working, but our customer wants to implement AT commands which we need to send in order to configurate the target device.
We are currently using the CYW920706WCDEVAL dev kit and have the audio track working with the 'Headset' example and the AT command interface working with the 'Audio gateway' example. But the headset example uses a different BT profile which allows the audio track to work.
The headset example uses the handsfree profile in order to send and receive audio data and the Audio gateway example uses the SPP profile in order to send the AT commands neccessary.
the target device is the following:
According to the datasheet the target devices BT peripheral is described as below:
Bluetooth module:
• Bluetooth v2.1+EDR
• Bluetooth v4.x
Bluetooth audio:
• Headset profile (HSP)
• PTT extension to HSP support
Bluetooth data services:
• Serial Port Profile (SPP) for data connectivity with
body-worn printers/scanners
• Dial-up networking (DUN)
• Discovery mode
• Generic attributes profile (GATT)
• Hardware-ready for:
– Object push profile
– Heart device (heart rate & temperature)
– Battery service profile
– Devices identity profile
– MAP
– HID
– HoG
Bluetooth trusted device, auto re-connect
Is it possible for the CYW20706 to do this simultaneously?
With kind regards (and hope)
Richard.
Show LessDear Supports,
We are developing with CYBT-413034-02 module for RFID POS as shown in the attached board picture.
For this reason, we need iAP2 function verification, so we need iAP2 SDK.
Please let me know, how we can get iAP2 sdk package..
Thanks

Show LessHello, AnjanaM_61
I am using Cybt-413034-02 custom board. I am trying to interface spi communication with TFT display.
Can I use any gpio pin for spi communication?
My pins are:
Cs = P07
Sci = P02
Sdi = P13
Sdo = P17
2. I have connected directly TFT display pins to my cybt -413034 module pin? Is it okay?
Because when I connect my display I get 4.2V on HCI CTS pin?
And module remains in reset state? What is the problem?
On module ground pin I am getting a pulse. Attached below. What could be the error.
Thank you.
Show Lesshi madem/sir
here i need some solutions for for below questions,
1) there is any API for rebooting or restarting the cybt-343026 module.
2) some times bluetooth is not connecting or pairing properly (mainly when i am changing bluetooth name).
3) if module receiving 100 bytes of data (0x20/spaces) from PUART RX again it is returning the same data to the PUART TX.
thank you.
Show LessHi,
I found an API( wiced_bt_dev_status_t wiced_bt_ble_set_phy ( wiced_bt_ble_phy_preferences_t ∗ phy_preferences ) ) to configure the LE link to 1M or 2M.
And "wiced_bt_ble_phy_preferences_t" has a data field "remote_bd_addr". The "API Reference Guide" said "remote_bd_addr" is "Peer Device address".
Does this means "wiced_bt_ble_set_phy()" will set central device LE link?
If CYW20719 serve as perpherial device, how to set LE link of CYW20719?
Best regards.
Show LessGood afternoon
I am using the CYBT-213043-MESH kit
I need help with this code, we need help with BLE MESH
I can scan devices and I can send them by message through the mesh network
The problem in this code in the function:
void mesh_vendor_server_send_adv_data (uint8_t * bda, int8_t rssi), datps send very slow
The data is sent every 200 milliseconds, I want the data to be sent faster,
Can you help me to send this data as quickly as possible?
Please
can you please help me?
this is very urgent
Show LessHello.
My project requires pairing with PIN(fixed length 4).
I found following article but it is not compatible with CYBT-413034, I think.
PIN Setting During BT Connection - KBA225063
Please let me know appropriate API.
