Hello Everyone,

My company has made a custom board based on imx6ul for EFTPOS applications. We are using 1MW module in our product. Our interface is SDIO based. Schematic is as below.

I get the following error after bootup.

Hi there,

I am currently developing a Raspberry-Pi based product, which is using BLE (no Wifi). We need to CE-certify this product.

In order to do that, I need to be able to activate the direct test mode on the chip.

Which HCI command do I have to send? What are the OCF and the OGF and the payload for this command?

According to this document HCI Interface — Vendor Specific Guide 5.00.00 documentation  this is part of the vendor-specific commands.

Which are the correct commands for the chip I am referring to? How can I trigger this mode?

I also need to be able to count the number of valid received BLE packets. How can I do that?

Thanks and best regards,

Caroline

On running PI3B+ with Linux kernel 4.14.y as an AP (using wlan0), if protected management frame is enabled in the hostapd (ver : 2.9) with configurations as follow, the clients are not getting connected :

wpa=2

ieee80211w=2

key_mgmt=WPA-PSK

I could see the error in client that AP is not MFP capable. If ieee80211w=0 is used, STA is getting connected. Have anyone tried using protected management frame (ieee80211w=2) and get the client connected. Is this a known limitation or any firmware/kernel fix available. ?

Hi all,

Evaluating the CYBT-483039-02 module for use in a new design, I have the CYBT-483039-EVAL board plugged into a TI Beagleboard X-15 (running a minimally customized Yocto Warrior OS to add necessary Bluetooth tools) with Bluez5.50

Set up:

I followed this blog post to get a Bluetooth PAN network running: https://blind.guru/tag/bluetooth-pan.html under Bluez5.
I paired with a cheap USB-dongle connected to my PC (Ubuntu 18.04) and have been running iperf3 UDP tests.

On PC:

iperf3 -s

On the BB x-15:

iperf3 -c <IP-address> -t 120 -u

(Setting the test time to 2 minutes as the error does not occur consistently)

Error encountered:
(Copied from Syslog - all messages that were printed during the test)

After this, the module is unresponsive until power is cycled.

The module seems to work with TCP tests or at least I have not been able to reproduce the error.

I have tried to reproduce the issue with the CYBT module plugged into my PC (and generic USB dongle on the BB x-15) but have been unable to successfully establish a PAN network to even run a test.

Anyone have advice on why this is happening or how to fix?

Hi,

I want to make a wireless-repeater with a RPI3B+.

i could configure the RPI in client mode ( so the RPI connects to an AP), and also i succeeded to configure it as an AP bridged to the eth0.

But when i tried to set-up the repeater configuration with 'relayd' , it didn't work at all.

Hello . I wonder if Cypress  provide support for a2dp offload feature in Android  . The BT chip is 43455 . For now we use default configuration and sound transmitted to BT chip by UART . However audio is slightly choppy .

Thank you .

Is the calibration current documented anywhere ?? We see periodic ~20ms 600mA calibration current for BCM43353 and BCM4343W. Does not
seem to be documented in the chipset datasheet ...

600mA for 20ms is a problem for USB powered devices (500mA power limit).

Do all Cypress chipsets require this type of calibration current ??
