@skylin008:matrix.orgsky linAttatch the app file.Thanks!03:24:55
@artur.librecube:matrix.orgArtur ScholzThanks. It is more convenient if you share the code repository or as code snippet.08:08:20
@artur.librecube:matrix.orgArtur ScholzAre you switching the bus every 10ms ? See line 113 of https://gitlab.com/-/snippets/210295108:08:48
@skylin008:matrix.orgsky linThanks to for your kindly support!08:10:23
@skylin008:matrix.orgsky linYes, 10mS 08:10:33
@artur.librecube:matrix.orgArtur Scholz Also I am curious, did you implement queue in micropython? from p import queue 08:10:34
@artur.librecube:matrix.orgArtur ScholzMaybe that is too fast. Have you tried with a large delay, such as 1 sec and then shorten the duration stepwise? Do you see the same problem?08:11:26
@skylin008:matrix.orgsky linThis queue be to used for the Uart port. 08:11:30

Could be interesting for shayanmajumder for the CFDP port. Can you share more details please?
08:12:03
@skylin008:matrix.orgsky linok .I will delayed-enhancement between two CAN port switch.08:14:39
@skylin008:matrix.orgsky linThanks!08:14:49

@shambu2k:matrix.orgSidharth Shambu Artur Scholz: Can we use msgpack to implement the space packets as specified by ccsds for spp/usdlp ? 18:22:23
@gwohl:matrix.orggwohl changed their profile picture.18:29:20
@shambu2k:matrix.orgSidharth ShambuAlso is the ESP8266 MicroPython board fine for the demonstration? - https://docs.micropython.org/en/latest/esp8266/quickref.html18:43:41

@shambu2k:matrix.orgSidharth ShambuPyboard V1.1 is expensive18:49:29

@shayanmajumder:matrix.orgshayanmajumder Hello Sidharth Shambu ! It is best to avoid external libraries to pack the packets instead use native python bit shifting methods for this purpose. This will make easier to port to micropython. Also regarding the board I think ESP32 would be the best option as it is low-cost also it has WiFi capabilities along with more memory. 00:01:27

@shambu2k:matrix.orgSidharth ShambuWhich is the best way in python to create multiple variables in contiguous memory? I've been using bitarray so far, any better way?18:09:50

ok .I will delayed-enhancement between two CAN port switch.
any news? does it work with larger delays?

Maybe you can refer this commit. https://gitlab.com/librecube/prototypes/python-cfdp/-/commit/a2c260b31de2b8a9f62997243165a8b4bd535bcb

@amanem:matrix.orgAmanem00
hello [Artur Scholz](https://matrix.to/#/@artur.librecube:matrix.org)  sir  and respected everyone i had a doubt (sorry if it doesnt make sense) ,but what should a data receiver from satellite have inside as seen from hardware perspective , 
18:17:16
@amanem:matrix.orgAmanem00can a raspberry pi based receiver do that work of receiving data from cubesat or in general from satelliate ?18:18:50
@amanem:matrix.orgAmanem00hello Artur Scholz sir and respected everyone i had a doubt (sorry if it doesnt make sense) ,but what should a data receiver from satellite have inside as seen from hardware perspective , 18:19:19
@amanem:matrix.orgAmanem00anyone who could please reply for above question!18:58:35
@artur.librecube:matrix.orgArtur ScholzYour question is not clear to me at all. Please try to get a book or papers about satellite engineering to get an understanding of the basics of satellite communication.20:02:41
@artur.librecube:matrix.orgArtur ScholzOr have a look at https://upsat.gr/ and https://acubesat.spacedot.gr/20:11:36
