SG PINECONE FOREST 1604 Car Protocol?

Discussed in #920

Hi there,

does anybody know if the MPM already contains the protocol to drive the famous SG 1604 models from Pinecone?

I think with the new Radiomaster MT12 (4 in 1 version) a lot of request for suface models support might come up :-)

Thanks in advance,

Alex

Bind

C=42 Enhanced pid=2 S=Y A= 01 03 05 07 09 P(15)= 01 D0 06 00 00 81 00 00 00 69 5F C8 00 00 E8
Packet[0] = packet type, 01 = bind, 08 = normal
Packet[1..5] = normal packets address
Packet[6..8] = 00 unknown
Packet[9] = ESP 00..64..C8 (0..100..200)
Packet[10] = ST_TRIM 00..64..C8 (0..100..200)
Packet[11] = ST_DR 00..64..C8 (0..100..200)
Packet[12] = flags: 0x40 TH.REV, 0x80 ST.REV
Packet[13] = 00 unknown
Packet[14] = sum(Packet[0..13])
RF Channels 45,59,52,67 (42?, 49?, 56?, 64?)

Normal

TX:

C=42 Enhanced pid=1 S=Y A= D0 06 00 00 81 P(15)= 08 64 64 00 00 00 00 00 00 69 5F C8 00 00 60
Packet[0] = packet type, 01 = bind, 08 = normal
Packet[1] = ST 00..64..C8 (0..100..200)
Packet[2] = TH 00..64..C8 (0..100..200)
Packet[3] = CH4 00..64..C8 (0..100..200)
Packet[4] = CH3 00..64..C8 (0..100..200)
Packet[5..8] = 00 unknown
Packet[9] = ESP 00..64..C8 (0..100..200)
Packet[10] = ST_TRIM 00..64..C8 (0..100..200)
Packet[11] = ST_DR 00..64..C8 (0..100..200)
Packet[12] = flags: 0x40 TH.REV, 0x80 ST.REV
Packet[13] = 00 unknown
Packet[14] = sum(Packet[0..13])
RF channel ??? -> Only 1 channel used, how is this negotiated?
Packets period 9ms

TX is also sending empty packets which looks like right after the main/above packet:
C=42 Enhanced pid=1 S=Y A= D0 06 00 00 81 P(0)=

RX response:

C=59 Enhanced pid=1 S=Y A= D0 06 00 00 81 P(15)= 10 00 03 FF FF B8 CE 0A 6C 37 FC 31 D7 06 58
C=64 Enhanced pid=1 S=Y A= D0 06 00 00 81 P(15)= 10 00 03 FF FF B8 CF 0A 6C 37 FC 31 D7 8E 58
No idea why the packet values changed
Packet[0] = packet type, 01 = bind, 08 = normal, 10 = rx
Packet[1..14] = unknown...
RF channel ??? -> same as normal
Transmit every 14-15 normal packets

Any updates on this? When will the protocol be implemented?
