Before this commit, there was no way to set a different max hop count
for unscoped messages.
Now with this change, by defaul it tracks the flood.max setting, until
a user provides a flood.max.unscoped value, which tax precidence for
packets if ROUTE_TYPE_FLOOD is true.
This is a consolidation of my changes for BME680 on RAK4631 nodes.
I will close my other PRs related to this and link back to this one.
*Background on change:*
This change replaces the Adafruit BME680 driver on RAK4631 with the
Bosch BSEC library. Other boards continue to use the existing
Adafruit path via ENV_INCLUDE_BME680.
This makes the IAQ portion of the sensor functional, and more accurate.
It also contains the math and/or CayenneLPP fixes from my other PRs.
The Bosch code also appears to handle calibrating sensor aging as well,
whereas the Adafruit code is just looking at blind values that can drift
with time. Pretty cool to see this shooting out useful data!
RAK4631 platform.io is set to override to ENV_INCLUDE_BME680_BSEC while
leaving the Adafruit code for other node types. (If this becomes applicable
for other node types in future, awesome! I just don't have hardware
to test against.)
Using the BSEC library introduces IAQ sensor calibration, and saves
the calibration state periodically so it does not have to calibrate
again later.
At startup the IAQ sensor takes 30 minutes to heat and to hit a baseline,
then starts calibrating. Once calibrated, it will save those settings
and will only write settings again if calibration falls back and restores
back to state 3.
This fix also has the gas resistance math fix that was in
[pull 2146](https://github.com/meshcore-dev/MeshCore/pull/2146) so
the adafruit path also can at least show accurate values instead
of looping negative.
Also includes the fix from [pull 2149](https://github.com/meshcore-dev/MeshCore/pull/2149) so the pressure output isn't truncated to 1hPa steps.
*Fixes/Changes:*
- Add bsec_config_iaq[] with the 3.3V/3s-LP/28d calibration profile
- BSEC init applies setConfig() for voltage-correct heater targeting
- IAQ, heat-compensated temperature/humidity, pressure, and altitude
reported over CayenneLPP
- IAQ accuracy reported as analog input over CayenneLPP (0,1,2,3)
- Calibration state persisted to /bsec_state.bin on nRF52 internal
flash; written only when iaqAccuracy improves to >= 2, should
keep write frequency well within flash endurance over device lifetime
- Fix non-BSEC query_bme680: float pressure division, addGenericSensor
for gas resistance (was addAnalogInput, overflows at > 327 Ohm)
- loop() correctly gated for both GPS and BSEC-only builds
- Add fix_bsec_lib.py extra_script to resolve nRF52840 hard-float ABI
mismatch in Bosch's PlatformIO packaging, silly Bosch
One general note outside of this code change: I noticed while BME680
_functions_ in companion nodes, since companion nodes run Bluetooth,
BLE preempts the CPU, and can do so mid-I2C-transaction.
This can cause the BME680 to see an anomaly and drop calibration and
start a recalibrate. This is behavior that will exist (and has existed)
regardless of using the Adafruit or Bosch paths.
This particular companion behavior does not seem to occur in sensor
or repeater nodes since their BLE is off. Probably affects other
I2C devices as well.
*Tests:*
- RAK19003
- RAK19007
- RAK19001
- repeater, sensor, companion
Framework for upcoming variant-specific PRs that add LED feedback during boot. The hook gives users visual cues that the device is busy and
shouldn't be interacted with until startup completes.
Extract the inline cursor-walk in handleRegionCmd into file-local
helpers (skipSpaces, rtrimSpaces, takeToken, splitNameJump,
processRegionDefSegment), grouped immediately above the consumer.
Behavior is identical; addresses PR #2540 review feedback on
readability.
Tighten the region def docs: collapse five Note callouts into three
grouped paragraphs (Behavior / Existing regions / Limits), add a
case-sensitivity caveat plus an error example, note the cursor reset
between split commands, and use generic placeholder names.
Add a new command `region bulk` for defining region hierarchies in a single line. This command allows users to create multiple regions in a single message. Updated the documentation to include usage examples and detailed parameter descriptions.
This slipped through in PR #2327 and I noticed because the TechoBoard.h
for my variant doesn't include the Wire header, so the source file
in question does not coincidentally obtain a copy.
The `::init` method in the Adafruit ST7789 library is responsible to
initialize the device. This includes performing a reset, which can be
found in the Adafruit source for `Adafruit_SPITFT`.
Before this change, MeshCore performed its own ST7789 display reset
sequence, which consisted of three steps.
* Pull reset low
* Wait 10ms
* Pull reset high
Importantly, there was no fixed delay after pulling reset high. The
ST7789 driver requires a delay (T<sub>RT</sub>) of 5ms in Sleep In Mode
and 120ms in Sleep Out Mode before it will properly receive commands.
When `Adafruit_SPITFT` resets the device after MeshCore has already
reset it, the mandatory time may not have elapsed, leading to strange
behavior. In the author's case, this issue caused the initial
`fillScreen` to fail, such that the display showed an uninitialized
framebuffer.
This removes the MeshCore delay, leaving the responsibility of reset to
`Adafruit_SPITFT`, where they have the correct delays in place with
extra safety margin. The change was briefly tested by Josiah VanderZee
and Ben Zignego on a custom hardware build using an nRF52840 Dongle and
an Adafruit 4311 TFT display. The user button seemed to behave
strangely, but the display looked correct.
USE_LR1110 was missing from the preprocessor guard in CommonCLI.cpp,
causing both get and set to fail silently on T1000-E:
- get radio.rxgain returned the full radio config string (fell through
to the memcmp("radio", 5) branch)
- set radio.rxgain returned "unknown config" (no branch matched)
Fix: add -D USE_LR1110 to variants/t1000-e/platformio.ini and include
USE_LR1110 in the #if guard on both get and set branches.
CustomLR1110Wrapper already implements setRxBoostedGainMode() and
getRxBoostedGainMode() via the RadioLibWrapper virtual interface,
so no radio-layer changes are required.
Tested on T1000-E: get/set/persist all confirmed working.
