STM32CubeMonitor-RF: Scripting BLE Tests

[connoisseur_de_mimi]

I want to use STM32CubeMonitor-RF's scripting feature to automate BLE tests, but I'm having troubles right from the start: 

Send(ACI_GAP_CREATE_CONNECTION;0x01D0;0x01D0;0x00;<client address>;0x00;0x0040;0x0040;0x0000;0x015E;0x0015;0x0015)
Wait(500)
Send(ACI_GATT_DISC_ALL_PRIMARY_SERVICES;<connection handle>)

ACI_GATT_DISC_ALL_PRIMARY_SERVICES needs a connection handle, which is only known at runtime, it would need to be extracted from a response to the ACI_GAP_CREATE_CONNECTION command. is this possible, or is it possible to set the handle to a constant value?

Hello @connoisseur_de_mimi, no possibility to extract handle from response nor to set in a constant value. In most cases, handle does not change in between script executions loop, need to get it value at first execution and use this value in script.

Unfortunately this seems not to work. Consider this simple script:

# Script recording starts on 11/12/2025 19:25:34
Send(ACI_GAP_CREATE_CONNECTION;0x0004;0x0004;0x00;0x000000000000;0x00;0x0006;0x0006;0x0000;0x000A;0x0000;0x0000)
Wait(500)
Send(ACI_GATT_DISC_ALL_PRIMARY_SERVICES;0x080A)
Wait(1000)
Send(ACI_GAP_TERMINATE;0x080A;0x13)
# Script recording ends on 11/12/2025 19:26:40

The first run is successful:

runs after that fail:

unless the connection handle is manually incremented. 

CubeMon-RF log file attached.

You can use Loop to increment the connection handle

 

Loop (CHandle, 0x080a, 0x0EFF)

Send(ACI_GAP_CREATE_CONNECTION;0x0004;0x0004;0x00;0x000000000000;0x00;0x0006;0x0006;0x0000;0x000A;0x0000;0x0000)
Wait(500)
Send(ACI_GATT_DISC_ALL_PRIMARY_SERVICES;[CHandle])
Wait(1000)
Send(ACI_GAP_TERMINATE;[CHandle];0x13)

Pause("Validate for next loop")

EndLoop

 

I don't know the the exact condition to avoid ConnectionHandle increment on remote device.
