Hi!

I wanted to try this sample with my Wireless Starter Kit, but I could not configure the soc-empty-rail-dmp sample app for the BRD4302A radio board with a BGM121. Please let me know how I can build it.

As the log of reconnection shows our BGM central remembers the bonding.

bonding enter: bonding handle 1, remote device 0xe0:0xc7:0x67:0xbc:0x45:0x4d, address type 0 

I do not know how I can see the detail on iOS, but at least the Settings->Bluetooth page of my iPhone shows "Empty Example" under MY DEVICES, which is quite normal  for a bonded device. Since I do not handle bonding information in the iOS sample program explicitly, I have no reason to think that any would be lost.

Hello!

I am experiencing a mysterious symptom. I use a BGM 121 starter kit with a Bluetooth Software 2.12.3 central app (central_security_demo.sls) and an iPhone SE with an iOS 13.1 peripheral app (ios-cbperipheral-example-master.zip). 

The bonding process is normally completed in security level 4.

Then I reset the BGM board and they connect again with bonding but I can increase their secure level only to 2.

How can I get its security level to 4 in this case?
 

Thank you for clarifying the situation, tmonte! If the limit is set to default 14, the value of bonding handle remains under 14?

Hi!

I am writing a firmware for BGM121 which deals with multiple bondings. The number of bondings is limited to 14, but bonding handles can range from 0 to 31. I want to know whether bonding handles can be really that big or cannot be bigger than 14 or the max_bonding_count set by the cmd_sm_store_bonding_configuration. Thanks in advance.

Hi,

Hi,

The project in the zip file is using the old SDK. 

But you can use the attached .c and .h files in newer SDKs.

Hi, Balázs!

Thank you for your advice. After a little work (I had to forge uart_echo.h which is missing &c.) now my BGM121 on SLWSTK6101C flawlessly echos input from uart!
