Hi,
Our customer is ready to produce mass product, but the manufacturer has missed to set utilizing the peripheral uart pins.
Customer said that peripheral uart was necessary to test in the step of manufacturing.
So customer would like to know it is possible to use HCI UART pin as peripheral uart pin. As I know it is impossible to use so that.
Nevertheless, is there any possibility?
Thanks,

Show LessHello,
I am using the BCM20736S on a custom board running WICED SDK2.1.1. When a brown-out/low-voltage condition occurs, I want to handle the interrupt and quickly put the application into a 'safe' state before a reset. Is brown-out detection via interrupt supported?
Show LessHi,
I'm trying to use the Windows OTA upgrade app, but the application seems to hang. I'm using a Window 7 machine with a Bluetooth stack I downloaded from the Broadcom website:
Bluetooth Software Download | Broadcom
Here is my procedure:
1) Pair the device with the Win7 box via "Device and Printers" -> "Add a device" and click on my LE device pre-programmed with the "ota_firmware_upgrade" App
2) Run "WsOtaUpgrade.exe ota_firmware_upgrade-BCM920736TAG_Q32-rom-ram-Wiced-release.ota.bin"
3) The following dialog pops up and I click start and it gets to a transfer status and just sits here forever:
Looking at the Frontline BLE sniffer, I don't see any LE traffic coming through. When I click on the Device in "Device and Printers", I get this:
So it seems to me that I may not be using the right stack. Can somebody who has gotten the OTA upgrade to work on windows 7 comment? Or perhaps give me your procedure that worked for you?
Thanks in Advance

====UPDATE:==============
So I was able to get the OTA upgrade to work on Win8 machine which has the LE stack built in. So for those having issues with Win7, try finding a Win8 machine. The link is stable enough for the OTA upgrade to succeed
Show LessHi,
I have just read the following article in the EEtimes, and my question is.... does Broadcom have any plans to support the new standard, in any of their future modules, as this would be very favourable for us as a company, as it seems to address the security hole in the pairing process. Thanks in advance.

Show LessHi There,
We are trying the 20737 SoC solution by now. According to the product design, we have to use all of the SPI1/SPI2/UART/UART2/I2C and external flash. The following picture is the pin assignment on the system.
I have go through the following pages on this topic:
BCM20736S I2C, PUART and SPI comms
But the pin assignment seems complicated.Please help to review if it is doable.
Another question is that, if we use 20737 SiP module, any possible to use the I2C interface?

I see several similar questions, but I didn't see a conclusive answer.
I want my app to periodically change the MAC address of the beacon. I don't need to control the new MAC address; random is OK.
One of your competitors calls this "peripheral privacy" - in case that helps find the feature.
Does Broadcom have this feature?
Show LessHello,
Is there any documentation on scheduling policy of BLE stack?
The BLE Master needs to schedule connection window as per the established connection parameters.
And, if the scan is enabled on the Master with the conflict timing parameter,
I would like to understand how Broadcom BLE stack prioritizes the conflicting request.
Let's say, the connection interval is 10 ms and the connection window is 2.5 ms.
And, the scanning window is configured as 62.5 ms (100 slots) with around 1 sec scanning interval.
In this case, the Master skips the connection window and give the priority to the scanning window?

Hi,
I would like to test A4WP_power_transmitter and receiver with BCM920737TAG WICED SMART development kit.
But I don't have Broadcom PMU (59350). Therefore I disabled BLEPRU_PMU_INF_ENABLE from PRU (Receiver side).
But I didn't see any ble link from transmitter monitoring using LightBlue app from iphone.
Please advise me how can I connect between PTU and PRU without Broadcom PMU (59350).
Thanks.
