Studio Bluetooth Forum Discussions

I am currently looking for a way to get an RSSI with a BLE connection.

There is "wiced_bt_dev_read_rssi" in the RSSI acquisition function of BLE, and this is the method of scanning, but I am looking for an easy method. (To return the RSSI value immediately when needed)

For example, for WIFI, I am looking for something like "wwd_wifi_get_rssi" function to get the connected RSSI value.

Please let me know if you have such API functions or variables.

BLEの受信感度(RSSI)の取得方法について

現在、BLE接続しているRSSI取得する方法を探しています。

BLEのRSSI取得関数に、「wiced_bt_dev_read_rssi」があり、これはスキャンする方法になりますが、簡単に取得する方法を探しています。（必要になった際に、即時RSSI値を返答するため）

例えば、WIFIであれば「wwd_wifi_get_rssi」関数のように接続されているRSSI値を取得するようなものを探しています。

そのような、API関数や変数がありましたら、教えてください。

Hi Forum,

We are using CYW20706 with WICED version 6.0, and we cannot upgrade to newer versions (route audio over uart no longer supported).

So we know there is a bug in WICED 6.0 where RSSI reading from a BLE scan can turn out to be positive. We were dropping those data points previously. Now we are working on a new feature that relies on collecting RSSI readings for distance estimation, so ideally we can keep those data points.

Is it possible for us to correct/patch those positive readings in application code? Maybe there is a formula?

Thanks,

LJ

There is a supervision timeout that determines the disconnection of BLE, but I have three questions.

◆ QA

1. Is it ok to recognize "conn_supervision_timeout = 400" when the supervision timeout value is 4 seconds?

2. Is it all right to recognize the GATT event “GATT_CONNECTION_STATUS_EVT” 4 seconds after the BLE disconnection is detected?

3.2. In relation to, when I tried to operate with the following procedure, "GATT_CONNECTION_STATUS_EVT" event was notified about 2 seconds later.

I would like to be notified of the disconnection event 4 seconds after BLE disconnection. If there is a setting method, please let me know.

  ● Operation

  1) BLE connection from smartphone

  2) Turn off your smartphone

◆ wiced_bt_cfg.c settings

.ble_scan_cfg =

{

...

.conn_supervision_timeout = 400,

◆Environment

・WICED SDK 6.4.0

・ThreadX

Hi,

I have a control on my phone using client control, but I didn't succeed to connect to the audio channel.

I tried to use Android phone, but it connect and disconnect shortly after.

With IPhone I get the following error:

client control- AG Response: ERROR Num: 0 Params:

Hi all,

I want to ask for a question as topic, I know a data's logical address is 0xFF000C00, and how can i get the physical address?

Thanks

Development environment:

Windows 8.1 pro

Platform: CYBT-423028-02

IDE: Wiced Studio 6.2.1

(1)On any button change on Interrupt would work even if the internal pull-up/pull-down resistor is off/disabled? and please note if there is no external pullup or pulldown resistor used.

(2)How much current will be drawn by the internal pull-up resistor enabled in active mode?

(3)How much current will be drawn by the internal pull-up resistor enabled in sleep mode?

(4)How much latency will be for internal RTC? not used external 32Khz crystal.

您好，

我在测试蓝牙链接的时候，发现有时会出现connect失败的情况。我的做法是在scan到蓝牙设备后，通过hci command命令（connect）去建立链接，请问什么情况下会出现connect失败？

下面是我抓到的connect err的log

hello can you help me

I have a program that scans ble devices like cell phones and I can show them in uart but I want to send this data by ble mesh to a cybt-213043. mesh provision client

Can you tell me what examples can I use or give me some advice?

Question 1:

I'm trying to solve this problem, but I can't understand how to configure GPIO for Matrix keys. From below the API

Is there any predefined GPIOs which are used for Matrix key interface?

/////////////////////////////////////////////////////////////////////

/// Configure GPIOs for keyscan operation. Note that only GPIOs

/// that are in the matrix are configured for keyscan operation.

/// GPIOs that are not part of the scan matrix are left alone.

///

/// \param -none

///

/// \return - none

/////////////////////////////////////////////////////////////////////

void wiced_hal_keyscan_config_gpios(void);

Question 2:

Is it a write way to read any keypress event for 4x4 keypad?

What I am trying is,  connecting a 4x4 matrix keypad with CYW920719Q40EVB-01 dev kit on J3 -J4 connector from D0 - D8 (where D3 NC) ,

And configured pins for 4x4 Matrix keypad, where D0 - D8 are mapped to pins of chip i.e. D0: P34, D1: P33, D2: P00 ... .. D8: P06

and then trying to read if any key press ? like if P34 pin is  detected pressed I want to print 1 Num Pressed in debug log. if P33 then 2 num is pressed and so on.

APIs I might need to start with .

/* matrix keypad  Mia  driver intruupt init*/

      wiced_hal_mia_enable_mia_interrupt(TRUE);

      wiced_hal_mia_enable_lhl_interrupt(TRUE);//GPIO interrupt

/* matrix keypad  Keyscan  driver  init*/

  wiced_hal_keyscan_configure(KEYSCAN_ROWS, KEYSCAN_COLS);  // (4,4)

   wiced_hal_keyscan_init();

And by using wiced_hal_keyscan_is_any_key_pressed() function confirming if any keypress event generated or not.
