hi Marcel,

Can you upload your python script to demonstrate how to reproduce the issue?

hi Marcel,

The system_boot event might be caused by NCP target device reset, after that, it will report the event to indicate that the device has started and the radio is ready.
Please have a test with the code example below.

#!/usr/bin/python3

# import modules used here
import sys
import bgapi

connection = bgapi.SerialConnector('COMx')
node = bgapi.BGLib(connection, '/Applications/Simplicity Studio.app/Contents/Eclipse/developer/sdks/gecko_sdk_suite/v3.2/protocol/bluetooth/api/sl_bt.xapi')
node.open()
node.bt.system.reset(0)

def sl_bt_on_event(evt):
  global node
  if evt == 'bt_evt_system_boot':
    print("booted, start scanning...")
    node.bt.scanner.start(1,2)

  elif evt == 'bt_evt_scanner_scan_report':
    i = 0
    while i < len(evt.data):
        field_len = evt.data[i]
        field_type = evt.data[i+1]
        if (field_type == 0x09):
            print(evt.data[i+2 : i+field_len+1])
            if (evt.data[i+2 : i+field_len+1] == bytes('PyBGAPI Example','utf-8')):
                node.bt.scanner.stop()
                node.bt.connection.open(evt.address, evt.address_type, 1)
        i = i + field_len + 1

  else:
    print(evt)

while True:
  try:
    evt = node.get_events(max_events=1)
    if evt:
        sl_bt_on_event(evt[0])
  except (KeyboardInterrupt, SystemExit) as e:
    if node.is_open():
        node.close()
    print("Exiting...")
    sys.exit(1)

Thanks

hi CG,

One more comment is that the Bluetooth SDK contains a generic NCP Host example project for the PC, you can find it in the folder below. It demonstrates how to send BGAPI commands to the target device and process the event reported from the NCP target. 
c:\SiliconLabs\SimplicityStudio\v5\developer\sdks\gecko_sdk_suite\v3.x\app\bluetooth\example_host\empty\

Yes, the “Bluetooth - NCP” example does not contain a GATT database, and the host software can build the GATT database dynamically. It is recommended for most of the use cases because the target code does not need to be modified and synchronized with the Host code when the GATT database is updated.

Thanks

hi Marcel,

I can get the event with the code snippet below.

Thanks

hi Ivan.

If you are using the SSv5 with v3.x.x SDK, you can follow the steps below to enable the debug log

Install "IO Stream: USART"
Configure the "Board Control", and "Enable Virtual COM UART"
Install "Log" components
Add the header file #include "app_log.h", and output the log using the API "app_log_debug()", "app_log_info()" or etc;

Thanks

hi Bing,

I think you already raised a technical support case for this question, and I just copy the answer there for your reference.

The command system_set_tx_power can be used to set the maximum TX power, but the value which is actually set by the Bluetooth stack may not be the same as the input to the command.
Even Adaptive Frequency Hopping (AFH) is enabled, that not mean you can get a +20dBm Tx power, it will handle by the stack.
Refer to KBA_BT_0405: Bluetooth Tx power settings, see section "Tx power for data packets".

Thanks

Hi Alexandre,

Yes, the LE Isochronous Channels feature is not yet supported. If you want to get the information about the roadmap, please feel free to contact our sales team.

Thanks

YK is mostly right, except that it's not simultaneously in the literal sense because you cannot send packets on different frequencies at exactly the same time. The packets are sent with a small delay in between them which can vary depending on whether you are sending scannable advertisements or not, and if you are then it also depends if a central device sends a scan request to which the stack will respond to with a scan response.

More info in the Bluetooth 5.2 core spec, Vol 6, Part B, section 4.4.2.

hi Timothy,

Sorry for missing this post. I was wondering can you reproduce the issue with the bluetooth only example, such as soc-empty? 
For the error while calling the API "sl_bt_advertiser_set_data", can you show me the code snippet for setting user-defined data in advertising packet?

Thanks

hi Lucas,

I just checked with the v3.1.1 SDK in SSv5, the *.bat script works fine and it can generate the application.gbl correctly.. 

Did you do any changes with the *.bat script, and how about the other projects?

Thanks
