QingPing CGH1 & M5Stick-C

alfista2600 · March 1, 2022, 2:37pm

Hi - I bought a few of these sensors and I’m trying to get them to work with a M5Stick-C using 0.9.10.

I saw that you need to change two parameters when compiling to make sure it is responsive - I think they are.

#ifndef Scan_duration
#  define Scan_duration 1000 //define the time for a scan
#endif
#ifndef BLEScanInterval
#  define BLEScanInterval 52 // How often the scan occurs / switches channels; in milliseconds,
#endif

If I set BLEScanInterval to 1 I get a number of Nimble errors. If I leave it at 52, the Stick panics:

Using '/dev/cu.usbserial-85528FEF8B' as serial port.
Showing logs:

Any thoughts? Is there a pre-compiled binary somewhere I could grab that would work?

DigiH · March 1, 2022, 2:55pm

Hi alfista2600,

have you tried setting TimeBtwRead to 0, instead of the BLEScanInterval which I would leave as is, or try the precompiled/ready configured esp32dev-ble-cont environment in platformio.ini.

I think you might have mixed up the TimeBtwRead and BLEScanInterval parameters

Hope this helps

alfista2600 · March 1, 2022, 3:47pm

Thanks @DigiH - I’ll give this a try. I did feel like I maybe had the settings wrong…

alfista2600 · March 1, 2022, 5:45pm

Thanks again, and esp32dev-ble-cont installed via Chrome works just fine from the bluetooth perspective, but unfortunately it doesn’t retain wifi settings for some reason, and I can’t re-enter them either.

I wipe the device first with M5Burner. Then do the install. However after I power cycle to move it, it goes back into AP mode. When I connect to the AP again, it shows that it saved the MQTT host and device name, but it forgot the Wifi settings… and won’t save them if I enter them again.

DigiH · March 1, 2022, 6:36pm

Hmm, not sure what might be the problem there, someone else might know if there is an issue with that. I only ever used the WiFi MQTT entering mode the first time I discovered OMG. Since then I hard code them when doing the builds in platformio.

Since you have previously compiled with platformio maybe try the same with extending the esp32dev-ble-cont environment.

Original in platformio.ini

[env:esp32dev-ble-cont]
platform = ${com.esp32_platform}
board = esp32dev
board_build.partitions = min_spiffs.csv
lib_deps =
  ${com-esp.lib_deps}
  ${libraries.wifimanager32}
  ${libraries.ble}
  ${libraries.decoder}
build_flags =
  ${com-esp.build_flags}
  '-DZgatewayBT="BT"'
  '-DLED_SEND_RECEIVE=2'
  '-DLED_SEND_RECEIVE_ON=0'
  '-DGateway_Name="OpenMQTTGateway_ESP32_BLE_C"'
  '-DTimeBtwRead=0'
  '-DScan_duration=1000'
  '-DAttemptBLECOnnect=false'

extend it like this

[env:esp32dev-ble-cont]
platform = ${com.esp32_platform}
board = esp32dev
board_build.partitions = min_spiffs.csv
lib_deps =
  ${com-esp.lib_deps}
  ${libraries.wifimanager32}
  ${libraries.ble}
  ${libraries.decoder}
build_flags =
  ${com-esp.build_flags}
  '-DZgatewayBT="BT"'
  '-DLED_SEND_RECEIVE=2'
  '-DLED_SEND_RECEIVE_ON=0'
  '-DGateway_Name="OpenMQTTGateway_ESP32_BLE_C"'
  '-DTimeBtwRead=0'
  '-DScan_duration=1000'
  '-DAttemptBLECOnnect=false'
  '-DESPWifiManualSetup=true'
  '-Dwifi_ssid="NETWORKNAME"'
  '-Dwifi_password="NETWORKPASSWORD"'
  '-DMQTT_SERVER="192.168.x.x"'
  '-DMQTT_USER="your_username"'
  '-DMQTT_PASS="your_password"'
  '-DMQTT_PORT "8883"/""1883""'

MQTT_USER, MQTT_PASS and port 8883 if your MQTT broker requires secure connections, otherwise port 1883 and no username and password.

All the best.

P.S.: Looking through platform.ini I find that the esp32-m5stick-c-ble environment has some extra lib_deps and build_flags

lib_deps =
…
${libraries.m5stickc}
…
build_flags =
…
‘-DZboardM5STICKC=“M5StickC”’
…

so adding these to the virgin esp32dev-ble-cont or adding

  '-DTimeBtwRead=0'
  '-DScan_duration=1000'
  '-DAttemptBLECOnnect=false'

to esp32-m5stick-c-ble environment might actually not need the hard coded WiFi and MQTT details.

Would be good if you let us know what you end up with

alfista2600 · March 3, 2022, 2:40pm

Thanks - yes, I pieced together your instructions and got it working properly, adding the additional parameters to the esp32-m5stick-c-ble section.

I am barely beyond a beginner using these tools so find the more I touch the less likely it is to work, which is why I avoided adding all the wifi stuff. Turns out that I needed to escape a character in my wifi password that I didn’t think I’d need to, which gave compilation errors in a section I didn’t think was related.

Appreciate the help!
