Hello,

I have a problem with my Sinotrack tracker ST-901M.
I use RAHUVIK.

When i send my command Block device (fuel pump cut), tracker bug and reboot.
Actually the original payload is : S20,000000,1,1

{"channel_id":1184557,"device_id":XXXXXXX,"event_code":332,"executed":true,"id":1743846967956588,"ident":"XXXXXXX","name":"custom","origin_id":XXXXXXX,"origin_type":11,"properties":{"payload":"S20,000000,1,1"},"response":"command sent and marked as executed without waiting for the answer","timestamp":1743846967.966818,"transport":"tcp"}

And after that i receive :

{"close_code":4,"connection_id":8893430640369416,"device_id":XXXXXXX,"duration":811,"error_text":"002dc0 [sinotrack.pvm:105:12] in @ascii_data_packet: {ext} invalid s20 result '000000'\n by [sinotrack.pvm:69:4] in @packet","event_code":301,"id":XXXXXXX,"ident":"XXXXXXX","media_traffic":0,"msgs":84,"origin_id":XXXXXXX,"origin_type":11,"recv":3956,"send":30,"source":"XX.XX.XX.XX:7168","timestamp":1743846968.649776,"traffic":{"conn":774332168,"field_boundary":104,"field_start":29,"packet_start":0,"parsed":29,"timestamp":1743846968.649631},"transport":"tcp"}

This is the protocol details given by sinotrack for my device :
