# Boltwood CS || protocol
================
## Sensor as receiver
* 0x01 - REQUEST_POLL - say that there's someone waiting for data
* 0x02 - FRAME_START - data frame start (ending with '\n')
Without getting REQUEST_POLL, sensor will send data for 5 times and sleep.
All given symbols go after FRAME_START:
* 'a' - ACK (should be sent by computer after each good data portion)
* 'm' - next text is command sequence following by CRC16 ('m' not used in CRC)
* 'n' - NACK (should be sent by computer after each bad data portion)
Commands (ending with CRC16\n)
* 'b' - close Roof
* 'c' - get calibration
* 'l' - get wetness calibration
* 't' following by 5 integers - set thresholds
* 't' without data - set default thresholds
After sending command wait a little for getting ACK ('A'). If none (or NACK), try again.
All received data will be sent back in 'Q' frame type.
## Sensor as sender
* 0x02 - FRAME_START
* '!' - PURGE_START
* '|' - MEMORY_DUMP_START
* '^' - BOOT_LOADER_START
All given commands go after FRAME_START:
* 'A' - ACK
* 'M' - report data frame
* 'N' - NACK
* 'P' - poll request (before FRAME_START there's one 0x00 byte)
### Report data frame types
* 'C' - termopile calibration
* 'D' - **sensor report**
* 'I' - reset
* 'K' - wetness calibration
* 'Q' - report a command received from the PC
* 'R' - roof close
* 'T' - thresholds
* 'W' - wetness data
>> debugging???
* 'X' - "X rhr %d %f", rhr, rainheatt (control of the rain heater)
* 'Y' - "Y %f %d %d", rainheatt, suppressrh, suppressrrh (direct setting of the rain heater target temperature)
* 'Z' - "Z %d %d %d", rainheatt, suppressrh, suppressrrh (direct setting of the rain heater PWM hardware value)
