Hi,
How many BLE peripherals can be connected over HCI on CYW43438?
Does this amount be limited by whitelist size or address resolving list size?
I try to get the size of whitelist and address resolving list size over HCI, but failed.
Thanks,
Tom

Hi Axel:
thanks, actually, The sixth BLE peripheral has fail rate when doing connection with central device according our test. So 5 should be a confirmed and stable connection number.

Hi Tom:

6 is the max number from what we tested in wiced board . And what is the meaning of your steps by HCI mode ?

Hi zhez,
Thanks!
Using hcitool under linux, like this:
$hcitool lewlsz
White list size: 128
$hcitool lerlsz
Can't read resolving list size: Input/output error(5)
or initiate a connection
$hcitool lecc <bdaddr>

Hi Tom:
what is the type of cyw43438 you are using now? Actually we have a mbt tool which can be used in Linux environment for HCI command input and test , but that is for manufacture test , don't know if it can match your whitelist test .
You can have a check on this link also: https://community.cypress.com/message/6034#6034
Manufacturing Bluetooth Test Tool
Overview
The manufacturing Bluetooth test tool (MBT) is used to test and verify the RF
performance of the Cypress Bluetooth Classic and Bluetooth Low Energy (BLE) devices.
Each test sends an HCI command to the device and then waits for an HCI Command
Complete event from the device.
To run the tests:
1. If using a combo (WiFi & BT) eval board, you must run the bt_mfg_test
sample app. This app configures the BT device to run in the HCI mode and
the HCI commands and events are passed through the STM mcu via the FTDI
serial device driver.
2. Plug the eval board into the computer and note the serial devices under
/dev that get assigned to the eval board. Two will be listed, e.g. ttyUSB0
and ttyUSB1. The ttyUSB1 is the HCI UART interface you will want mbt to
interface to. If the serial devices are not listed when plugging in the
eval board, refer to the following wiced community thread:

It seems there is no standard answer for the maximum number of simultaneous connections.
