ESPGeiger Serial Output
ESPGeiger has a software Serial interface allowing simple UART communication.
The default baud is 115200
Each command should be terminated with \r\n
Note that Serial commands are disabled on ESPGeiger-Log builds. This is due to the Serial RX pin being in use for the user input button.
Commands
| Command | Description | Example |
|---|---|---|
reboot | Reboot ESPGeiger | reboot |
resetwifi | Reset the WiFi credentials | resetwifi |
ratio | Set ratio for calculating μSv | ratio 151.0 |
cpm | Return current CPM value | |
usv | Return current uSV value | |
show | Enable 1-second CPM output | |
show N | Enable periodic output every N seconds (1-65535). Implies CPM. | show 5 |
show 0 | Disable periodic output (clears every field toggle) | show 0 |
show off | Same as show 0 | show off |
show cpm | Toggle CPM line inclusion in periodic output | show cpm |
show cps | Toggle CPS on periodic output | |
show usv | Toggle uSV on periodic output | |
show hv | Toggle HV on periodic output (ESPGHW only) | |
hv | Return current HV value (ESPGHW only) | |
duty | Set duty cycle (0-254) (ESPGHW only) | duty 50 |
freq | Set PWM frequency (100-9000) - usually not needed (ESPGHW only) | freq 6000 |
vratio | Set ratio for calculating HV value (ESPGHW only) | vratio 1000 |
voffset | Set offset for calculating HV value (ESPGHW only) | voffset -10 |
target | Set target CPM value for Test builds only | cpm 1234 |
Example Output
show 1 enables a line every second, CPM only by default:
CPM: 30
CPM: 32
CPM: 28
show 5 for every 5 seconds:
CPM: 30
CPM: 32
Toggle additional fields with show cps / show usv:
CPM: 30 CPS: 0.50 uSv: 0.20
CPM: 32 CPS: 0.53 uSv: 0.21
With show hv enabled on ESPGeiger-HW:
CPM: 30 CPS: 0.50 uSv: 0.20 HV: 412
CPM: 32 CPS: 0.53 uSv: 0.21 HV: 413
Toggle CPM off with show cpm for CPS-only output:
CPS: 0.50
CPS: 0.53
Turn it all off with show 0 — periodic output stops and the regular log verbosity returns.
