Re: [amsat-bb] Falconsat-3 upload problem
Hello all,
Got all your TESTING UPLOAD messages in loud and clear. My message to K4KDR didn't get send out. I'm still (re)searching about the cause of this. Later......

Hi Hans,
I was able to upload a message (to you!) on FS-3 last night/this morning, fully automated. So the satellite is evidently behaving OK.
Hope you get it figured out. Since I don't use Direwolf, sorry I can't give any suggestions.

Desensing is also not the problem: got the appropriate filters in place for that. Cheers,

In the next week or so I will change radios at my station so I can again use FS-3. Â I'll be better able to share current experiences with you.

Okay, many hours googling and reading later......... I came upon two documents with some relevant information. First this is from the document "Pacsat File Header Definition". As it already says, it give a definition:
-------BEGIN------- 3.1.9 body_checksum
id : 0x09 length : 2 data : unsigned int body_checksum
A 16 bit checksum formed by adding all bytes in the file body into a 16 bit variable, ignoring overflow. The <body_checksum> does not include the bytes comprising the PACSAT file header.
The <body_checksum> is primarily intended to detect mis-corrected multi-bit errors caused by Single Event Upsets in the PACSAT memory.
INITIALIZATION - The correct <body_checksum> must be supplied. -------END-------
I don't quite understand the second but last sentence: does the PACSAT memory get upset by my messages?
From "Pacsat Protocol: File Transfer Level 0" document more on the upload procedures:
-------BEGIN------- 7.4. Completion of Upload
7.4.1 Successful Upload Completion
When the server receives the DATA_END packet it will check the integrity of the file as far as possible. If the checks pass, the server will downlink a UL_ACK_RESP packet.
Packet: UL_ACK_RESP Information: none
After transmitting the UL_ACK_RESP the server uplink state variable is UL_CMD_OK. After receiving the UL_ACK_RESP, the client uplink state variable is UL_CMD_OK.
7.4.2 Failure Caused by Server Rejecting Upload
The server may reject an upload while the client is sending DATA packets (due to file system problems on the server) or after the client has sent the DATA_END packet (due to corruption of the file).
If the server must abort the upload while receiving DATA packets or after receiving the DATA_END checks fail, it sends the UL_NAK_RESP packet.
Information: 1 byte unsigned char err_code; <err_code> must be one of:
ER_BAD_HEADER - The file either has no PFH, or has a badly-formed PFH. ER_HEADER_CHECK - The PFH checksum failed. ER_BODY_CHECK - The PFH body checksum failed. ER_NO_ROOM - The server ran out of room for file storage before the upload was complete. The server will implement procedures to avoid frequently running out of room, but this cannot be guaranteed.
After transmitting the UL_NAK_RESP packet, the server uplink state variable is UL_CMD_OK. After receiving the UL_ERROR_RESP, the client uplink state variable is UL_CMD_OK. -------END-------
So I clearly get a UL_NAK_RESP packet with the ER_BODY_CHECK error.
I also downloaded the PACSAT Ground Station software source code from G0KLA (hello Chris). The hex code for the BODY_CHECKSUM is 0x09. If you search for that in the source code you come up with the file Crc16.java. My coding skills are very minimal, so I don't grok the code completely, but I do see something strange in that file Crc16.java:
-------BEGIN-------
String s = "HELLO";
byte[] bytes = s.getBytes();
//Crc16 crc = new Crc16(bytes); short cs = 0; for(byte b : bytes) cs += b & 0xff; System.out.println(cs);
PacSatField pf = new PacSatField(cs, 0x09); System.out.println(pf); } -------END-------
String s is probed for the number of bytes, then "converted" into variable cs, which is the PacSatField 0x09, iow the Body_Checksum. Now string s is simply "HELLO" and I don't see if this is hard coded or that this string changes according to the content of the message body. Any Java programmers here who want to help me look at it?
Any help appreciated. Cheers,
Hans

Sorry for the late reply. I've been a bit buried in other tasks.
I don't think I have seen this issue before. I have seen the issue were we keep requesting a file, even though it is fully downloaded, because FalconSat-3 changes the timestamps when it updates files. But I have not seen this issue. So I have logged it here: https://github.com/ac2cz/Falcon/issues/43
I'll check the code and see if I introduced an issue with some changes I did to fix another bug.
Can you send me the file that you have difficulty uploading? Or attach it to the github issue?

Okay, many hours googling and reading later......... I came upon two documents with some relevant information. First this is from the document "Pacsat File Header Definition". As it already says, it give a definition:
-------BEGIN------- 3.1.9 body_checksum
id : 0x09 length : 2 data : unsigned int body_checksum
A 16 bit checksum formed by adding all bytes in the file body into a 16 bit variable, ignoring overflow. The <body_checksum> does not include the bytes comprising the PACSAT file header.
The <body_checksum> is primarily intended to detect mis-corrected multi-bit errors caused by Single Event Upsets in the PACSAT memory.
INITIALIZATION - The correct <body_checksum> must be supplied. -------END-------
I don't quite understand the second but last sentence: does the PACSAT memory get upset by my messages?
From "Pacsat Protocol: File Transfer Level 0" document more on the upload procedures:
-------BEGIN------- 7.4. Completion of Upload
7.4.1 Successful Upload Completion
When the server receives the DATA_END packet it will check the integrity of the file as far as possible. If the checks pass, the server will downlink a UL_ACK_RESP packet.
Packet: UL_ACK_RESP Information: none
After transmitting the UL_ACK_RESP the server uplink state variable is UL_CMD_OK. After receiving the UL_ACK_RESP, the client uplink state variable is UL_CMD_OK.
7.4.2 Failure Caused by Server Rejecting Upload
The server may reject an upload while the client is sending DATA packets (due to file system problems on the server) or after the client has sent the DATA_END packet (due to corruption of the file).
If the server must abort the upload while receiving DATA packets or after receiving the DATA_END checks fail, it sends the UL_NAK_RESP packet.
Information: 1 byte unsigned char err_code; <err_code> must be one of:
ER_BAD_HEADER - The file either has no PFH, or has a badly-formed PFH. ER_HEADER_CHECK - The PFH checksum failed. ER_BODY_CHECK - The PFH body checksum failed. ER_NO_ROOM - The server ran out of room for file storage before the upload was complete. The server will implement procedures to avoid frequently running out of room, but this cannot be guaranteed.
After transmitting the UL_NAK_RESP packet, the server uplink state variable is UL_CMD_OK. After receiving the UL_ERROR_RESP, the client uplink state variable is UL_CMD_OK. -------END-------
So I clearly get a UL_NAK_RESP packet with the ER_BODY_CHECK error.
I also downloaded the PACSAT Ground Station software source code from G0KLA (hello Chris). The hex code for the BODY_CHECKSUM is 0x09. If you search for that in the source code you come up with the file Crc16.java. My coding skills are very minimal, so I don't grok the code completely, but I do see something strange in that file Crc16.java:
-------BEGIN-------
String s = "HELLO";
byte[] bytes = s.getBytes(); //Crc16 crc = new Crc16(bytes); short cs = 0; for(byte b : bytes) cs += b & 0xff; System.out.println(cs); PacSatField pf = new PacSatField(cs, 0x09); System.out.println(pf); }-------END-------
String s is probed for the number of bytes, then "converted" into variable cs, which is the PacSatField 0x09, iow the Body_Checksum. Now string s is simply "HELLO" and I don't see if this is hard coded or that this string changes according to the content of the message body. Any Java programmers here who want to help me look at it?
Any help appreciated. Cheers,
Hans

Hi Hans,
I was able to upload a message (to you!) on FS-3 last night/this morning, fully automated. So the satellite is evidently behaving OK.
Hope you get it figured out. Since I don't use Direwolf, sorry I can't give any suggestions.

I didn't write it directly, but I assumed from the description you would read that I indeed run full duplex (and to add to this: my system is Linux, not Windows). If not Direwolf will wait for a free window to throw out packets which will never happen because FS-3 is on all the time. No, everything is working, except for the problem I described before: all commands to the bird are heard and responded to, but uploading a message will fail.
Desensing is also not the problem: got the appropriate filters in place for that. Cheers,

Hello Hans, I have not been working FS-3 recently, since the IC-9700 will not do 9600 packet [iCom, please fix!!] :(   So I cannot comment on recent uploads. However, to add to Bob's thoughts--are you running full duplex?  It's critical. Also, is your transmit signal desensitizing your receive signal?  That is important, too.Â
In the next week or so I will change radios at my station so I can again use FS-3. Â I'll be better able to share current experiences with you.

Thanks to the hard work of Chris this issue has now been fixed. I just downloaded the latest version (v0.24) of PacSat Ground Station and was successful in uploading two messages. This was done on my Linux box (Kubuntu 19.04) with Direwolf v1.5 as soundmodem/PE. A flow chart of my setup can be found here: http://bx2abt.com/main/Falconsat-3.
Thanks again to Chris for writing this modern day PacSat software.

Sorry for the late reply. I've been a bit buried in other tasks.
I don't think I have seen this issue before. I have seen the issue were we keep requesting a file, even though it is fully downloaded, because FalconSat-3 changes the timestamps when it updates files. But I have not seen this issue. So I have logged it here: https://github.com/ac2cz/Falcon/issues/43
I'll check the code and see if I introduced an issue with some changes I did to fix another bug.
Can you send me the file that you have difficulty uploading? Or attach it to the github issue?

PacSatField pf = new PacSatField(cs, 0x09); System.out.println(pf); } -------END-------
String s is probed for the number of bytes, then "converted" into variable cs, which is the PacSatField 0x09, iow the Body_Checksum.
