How to pair a STM32WB55 BLE device via STM32CubeMonitor-RF with P-NUCLEO-WB55 dongle?

[DImre.1]

I'm not able to pair our application running STM32WB55 via STM32CubeMonitor-RF. Pairing with iOS sniffer apps are working. What are the settings and commands I shall apply in STM32CubeMonitor-RF?

Our device is using a 6 digit pin, bondle mode, MITM protection. Any other setting which might needed for P-NUCLEO-WB55 dongle?

Hi @DImre.1​ ,

An introduction to STM32CubeMonitor Tools Suite is provided in the wiki page.

Now for STM32CubeMonitor-RF, you have the UM2288 STM32CubeMonitor-RF software tool 

for wireless performance measurements.

Dear Amel,

These general links does not help. Moreover, the UM2288 does not contain any info about pairing method.

My issue after many tries:

1. I set IO capabilities to keyboard-display: Send(ACI_GAP_SET_IO_CAPABILITY;0x04)
2. I set up authentication data: Not sure if this is necessary on master side! Send(ACI_GAP_SET_AUTHENTICATION_REQUIREMENT;0x01;0x01;0x01;0x00;0x08;0x10;0x00;0x00000000;0x00)
3. Connect success
4. I'm not able to pair: Send(ACI_GAP_SEND_PAIRING_REQ;0x0801;0x00) even with last parameter 0x01 Force Rebound. Error message: Unknown connection identifier. But my connection id is 0x0801!

What do I miss?

Hi @DImre.1​ ,

In that case, I need to ask the help of our STM32CubeMonitor Expert @stephane.legargeant​ .

Hello!

I found the solution: I needed ACI_GAP_SET_AUTHENTICATION_REQUIREMENT with the following parameters: Send(ACI_GAP_SET_AUTHENTICATION_REQUIREMENT;0x01;0x01;0x01;0x00;0x08;0x10;0x00;0x0003640E;0x00). The 6 digit password was needed in hex!

I expected an event of password request, but I'm also fine with this solution that I set up authentication requirement with pairing code before connecting to the device.
