Studio Bluetooth Forum Discussions
Since CYW20719 supports DLE ( data length extension ), how could I send a large number of data? Is there an API in CYW20719 SDK for this purpose?
now I am not very clear about that how the LPN device is to be added into the Bluetooth mesh networking. as we know, the LPN device must need a friend node
to communication with other devices. now the LPN how to choose the networking friend node device. if the provisioning procedure of the LPN device requires the participation of the friend node.
now I download the mesh provision client firmware into the CYW20735Q60EVB-01 board and use the mesh client control to create a Bluetooth mesh networking.
I add a dimmable light device into the networking. the dimmable light can be controlled by mesh client control. finally I configure the mesh light ctl server to LPN node
the configuration as below:
.features = WICED_BT_MESH_CORE_FEATURE_BIT_LOW_POWER, // A bit field indicating the device features. In Low Power mode no Relay, no Proxy and no Friend
.friend_cfg = // Empty Configuration of the Friend Feature
.receive_window = 0, // Receive Window value in milliseconds supported by the Friend node.
.cache_buf_len = 0, // Length of the buffer for the cache
.max_lpn_num = 0 // Max number of Low Power Nodes with established friendship. Must be > 0 if Friend feature is supported.
.low_power = // Configuration of the Low Power Feature
.rssi_factor = 2, // contribution of the RSSI measured by the Friend node used in Friend Offer Delay calculations.
.receive_window_factor = 2, // contribution of the supported Receive Window used in Friend Offer Delay calculations.
.min_cache_size_log = 7, // minimum number of messages that the Friend node can store in its Friend Cache.
.receive_delay = 100, // Receive delay in 1 ms units to be requested by the Low Power node.
.poll_timeout = 10, // Poll timeout in 100ms units to be requested by the Low Power node.
.startup_unprovisioned_adv_to = 128 // Interval in seconds of the advertisments of unprovisioned beacon and service on startup. Value 0 means default 30 seconds.
when I want to add the device into the networking. the mesh client control output print messages is below：
it seems the provisioning procedure is failure, now I don't know how to solve this problem !
i am using CYBT-343026-01 module interfacing with msp430. i want to ask how to communicate both the device with RX and T pins or i need RTS and CTS pins aslo. and how to use hci commands?
thank you.Show Less
We have a development project to design a Pulse Oximeter capable of BLE and BR performance. Cypress module CYBT-423028-02 looks to be a good fit.
Question 1: Is the stack running on the CYBT-423028-02 or do I need to run the stack on a separate microcontroller?
Question 2: Our application requires a number of security features including secure boot which ensures that only authenticated software can run on the module. Does the CYBT-423028-02 support this?Show Less
I haven't been able to connect the node for a while from MeshClient.
Here is fragment of log:
17:58:37.744 Net transmit set addr:0001 count:3 interval:50
17:58:37.760 Net Transmit Status from:1 count:3 interval:50

17:58:37.775 Default TTL Status from:1 TTL:63 Received TTL:63
17:58:37.807 Beacon set addr:0001 state:0

Does exist a workaround.
In the mesh_sensor_publish_timer_callback there is following instruction:
meshmesh_sensor_current_value = mesh_sensor_get_current_value();
Here is definition of mesh_sensor_get_current_value function:
But I didn't find where presence_detected is assigned ???
Any comments ?
Actually the only option allowing MeshClient application (running on Windows) to receive messages from Sensor Motion node is to specify "all-nodes" value for "Send sensor measurement" parameter. But if I want Sensor Motion to send data only to MeshClient, how to proceed ?
I've observed that after about 3 min. the connection with Sensor Motion node breaks and Link Staus:0 appears in Log window.
Any comments ?
We would like to using evb J18 Uart to connect a main ic evb like microchip evb,
is there a way have simple this uart connection test using using wiced studio?
