FastSyncRead Error Code 6 on OpenRB-150

Hello there,
I am using OpenRB-150, Arduino V. 1.8.19 and was testing the ROBOTIS example fast_sync_read.ino. I only changed DXL Baud Rate to 1 Mbps as my 2XL-430 is setup to 1 Mbps. This example compiled and ran OK, SyncWrite worked fine, but fast_sync_read reported error 6. Can you help with fixing this error?


I have used regular Sync_Read and it works fine.

Thank You.
