Receiving Parsing Error about iridium-toolkit

[Sec42]

Both are normal.

"fft_burst_tagger :info: set_min_output_buffer on block 5 to 65536" is a message printed by gr-iridium. As it contains no bits, it's normal that iridium-parser cannot parse it.

The "Access code missing" messages indicate bits that do not contain the (error-free) access code, so it is telling you that it didn't parse these.
There is an option for iridium-parser --uw-ec which uses more cpu and tries to parse these lines that you can use. But be aware that it is more likely to contain further errors and may still fail parsing.

Alternatively you can also use --errorfree to just ignore all lines that can not be parsed.
