Problem with SDO Block Transfer (+workaround) #618
Description
Activity
Can you please post actual CAN logs of what appears on the bus? There should be some useful debug logging inside the canopen.sdo.client module as well.
I assume that when talking about the client, you mean this library and it is talking to an SDO server on an embedded device?
Server: STM32 based device that shall receive the data
Client: Win11 PC with Python App using this liblogging from canopen.sdo.client module:
`DEBUG:canopen.sdo.client:Reading 0x2000:17 from node 112 DEBUG:canopen.nmt:Received heartbeat can-id 1904, state is 0 DEBUG:canopen.sdo.client:Reading 0x2000:17 from node 112 DEBUG:canopen.sdo.client:Reading 0x1023:2 from node 112 DEBUG:canopen.nmt:Received heartbeat can-id 1904, state is 127 DEBUG:canopen.sdo.client:Reading 0x1023:2 from node 112 INFO:canopen.sdo.client:Initiating block download for 0x1F50:1 DEBUG:canopen.sdo.client:Expected size of data is 34680 bytes DEBUG:canopen.sdo.client:Server requested a block size of 127 DEBUG:canopen.sdo.client:Waiting for acknowledgement of last block...

Hi, if i try a SDO download with block transfer like in the docs, but without crc, i.e.
the transfer ends after one or two sub blocks. The last SDO from the client has the invalid payload=DD 00 00 00 00 00 00 00. The transfer is working without the 1024 chunk. Just use data = infile.read() or a chunk size of 7*1024.
