I have two bcm20732 board, one is BCM920732_TAG, the other is bcm20732s module.
When I use mbt tool to do RF character testing such as "mbt set_tx_freqnecy_arm COM39 1 2402 3", the tag board can return as normal like below:
C:\Disk_Driver\Firmware\WirelessModem\BLE\truck\WICED-Smart-SDK-2.1.0\Tools\mbt\Win32>mbt set_tx_frequency_arm COM39 1 2402 3
Sending HCI Command:
0000 < 01 14 FC 07 00 02 00 00 08 03 00 >
Received HCI Event:
0000 < 04 0E 04 01 14 FC 00 >
Success
But the bcm20732s module is without the "Received HCI Event" like this:
C:\Disk_Driver\Firmware\WirelessModem\BLE\truck\WICED-Smart-SDK-2.1.0\Tools\mbt\Win32>mbt set_tx_frequency_arm COM31 1 2402 3
Sending HCI Command:
0000 < 01 14 FC 07 00 02 00 00 08 03 00 >
What is the reason?

Is it in recovery mode? You have to have a valid image in the NV and the device must be in download mode for the MBT tool to work.

It is NOT i recovery mode, it's in HCI mode.
It can execute "mbt reset", but continuous carrier wave is failure.

After recovery, my BCM20732S module can download a valid image. Then, mbt tool can work fine.
Thanks.
