CANable Pro & candleLight_fw: doesn't work anymore about candlelight_fw

[fenugrec]

I observe two things here.

1- I can have similar behavior if there's just one CAN device (the candlelight) on the bus, i.e. no other device to generate the ACKs. [EDIT] candump sees 3 echo frames because the firmware succeeds in filling the 3 hardware mailboxes and assumes they are then transmitted fine . There is no checking to verify the mailboxes have indeed been processed, so this is expected.

2- "no buffer space available" : this is normal, and should rectify itself if you activate a second CAN node on the bus.

works fine with slcand

Are you saying a single slcan device shows echo'd frames even with no other node to generate the ACK ? That doesn't sound right.

@Ciusss89 anything new ? Have you tested with at least 2 devices on the bus as I mentioned ?

I miss your replay. I'm apologize for the delay! I will do a new test this weekend!
