Hello,
any options to open this issue/thread again?
from md380tools.
Mototrbo Packets with RAS basically fail the CRC check as i understand it. Maybe it is possible to "not care CRC"
Typical AMBE LC Block
Non RAS

1234,1234,1234,FF11The CRC no longer matches. since the CRC dosnt match - the radio ignores the packet and there is no rx unmute.
Is there any further work been made on RAS for the 380? Would the above work? Could that "ignore CRC" entry work if coded correctly? Remember, this is to RX only, not TX. How critical is the CRC check, and can it be bypassed?

The GD77 firmware hack completely ignores RAS, whilst I haven't looked at the chips of both radios, I don't expect it to be very difficult, especially if Mr. GD77 and Mr. 380tools link together. 🤷♂️
To note Travis advised me personally that he doesn't want much more to do with the project since the passing of his friend whom was also involved. If someone can fork it, make and test, Travis will include the additions on his pull once verified.

Closing this as no progress has been made since March. Add it to #370 if there's interest.

If someone able to understand the whole system. It is definitely beneficial to implement for tx also. I have motorola radios (tier2), sdr and both mmdvm repeater and hotspot, but unfortunately not motorola repeater atm. I will gladly help to test this feature.

Travis ! give a little help. with this option is really missing (PLEASE)
from md380tools.
This has nothing to do with hardware. The radio has to ignore crc header. OPENGD77 ignores ras decoder, but only older firmwares. New one are focusing on HAM.

Hello, is there any news about RAS support on md380 toolz?
