I'm trying to communicate with a bluetooth thermometer. It's not BLE, it uses serial ports. I've made it as far as receiving REQ signals from the device, but it requires a ACK signal or it cuts the connection after a few seconds.
The problem is, I can't decipher what the ACK signal is supposed to be. Going off the documentation, it says:
<ACK Format> ADH,01H
<REQ Format> ADH,00H,n The third byte of REQ is the can be multiplied by 0.01310547 to get the voltage of the battery
<Data Format> ADH,03H,1EH," IRSTP3xx.yyy.HhhSss,nnn,tt.t"+0D+0A xx: LotNo.(base 16) "01"~"FF" yyy: S/N(base 16) "001"~"FFF" ... ... Nothing in the Data Format mentions the first 3 bytes(?) either.
That's pretty much all I've got to work with. I'm trying decoding REQ with different encodings like ascii and utf-8 to see if I can get it to match the REQ format, and then use that same encoding to format and send ACK, but I haven't had any luck.
Is the format just in some kind of standard notation that I'm not familiar with?
