eelink protocol specifications

TSM7 years ago

Does anyone have the full eelink protocol specifications?
The ones that they publish are missing various commands. I had a problem where mine kept on saying it had crashed but after a special SMS message from the seller of the device (TK116) it now no longer does it.
That command is not listed in the documentation.

Also there are three commands that I need clarification

TIMER - GPRS Upload time
DELAY - Monitor delay ??? (what does this mean)
HBT - Heartbeat to server

HBT I know, just basic packets so server knows tracker is online
TIMER, I think this is the interval to upload GPS updates when there are no other Alarm triggers
DELAY, not sure but i think it may be how long an ALARM needs to be active before it sends updates.

Anyone know more info on how it all works.

Do you have a list of all the possable commands the TK116/121/119 support.
There are lots of hidden commands that are not indicated in the specifications, ie WARNING, SET etc.

Maybe I can send all the commands in my hand to you? Do you need it?
