Unable to indentify the protocol

Himanshu4 years ago

Dear Anton
I am unable to identify the protocol of this device. It look very similar to EELink (Because Start bit on both protocol is 0x67) but not working. The protocol document is as below

http://206.189.140.251/ProtocolET301.pdf

Kindly help please.

I think eelink should be the right protocol.

I think the device is not getting expected reply from server. Device connect with the server with login packet and then server is sending some data but it is not what the device expect. As device is not getting correct reply so it is not sending location data. The log is as below:

2020-07-02 21:23:50  INFO: [a24aa19a: eelink < 42.111.5.3] HEX: 6767070006000b0076035d
