Setting RawCAN data in pre-tx, python

[thebhef]

Using TSMaster x64, 2025.2.10.1308.

I'm trying to update the data of a message in the pre-tx event handler.

I've tried using the set_data, as documented in the TSMaster header

byte_index = 7
byte_value = 0x30
ACAN.set_data(byte_index, byte_value)

print(ACAN.data) # shows updated value in System Messages

I've also tried assigning the data, as documented in the TSMaster header

new_data = ACAN.data[:-1]
new_data.append(0x30)

ACAN.data = new_data

print(ACAN.data) # shows updated value in System Messages

The data is updated when I print the data field, but I don't see these changes reflected in the trace panel, or on the bus.

` new_data = ACAN.data[:-1]
new_data.append(0x30)

ACAN.data = new_data
print(ACAN.data) # shows updated value in System Messages
com.transmit_can_async_wo_pretx(ACAN)
com.block_current_pretx(Instance)` Please add these two functions and try again
