Enhanced the firmware versioning system by appending a build number
suffix when available, allowing for better tracking of published builds.
This change improves the OTA update process by providing clearer
versioning information in the embedded firmware string.
While working on some sensor code implementations, I ran into
some hard crashes that root-caused to the 4KB loop task stack
being exhausted.
Looking for various optimization schemes resulted in this relatively
low-lift fix. RAK3401 and RAK4631 both support hardware crypto.
Rather than loading in one of the two software crypto libs,
we can just use the onboard hardware. This is faster, should
consume less power, and in testing used a scant up to 700
bytes in the run loop vs 2.5-3KB per advert.
This change **only** affects advert verification processing, which
currently consumes a significant chunk of the 4KB run loop.
I figured such a change should likely be implemented in phases.
After soaking, this hardware crypto verification
process could be implemented across the entire MeshCore
cryptographic function on RAK nodes. Also possible other nodes
have available hardware crypto, however, I have not checked,
so future improvements may also exist there.
Tested on:
- RAK3401 RAK 1W
- RAK4631 19001
The SH1106 OLED on the LilyGo T-Beam Supreme V3 never lights up because:
1. The primary I2C bus (Wire) that the OLED, BME280 and magnetometer share
is never initialized. The PMU/RTC use Wire1 (via XPowersLib); nothing
brings up Wire on PIN_BOARD_SDA/PIN_BOARD_SCL, so the display driver
talks on the wrong default pins.
2. The OLED is at I2C address 0x3D on this board (0x3C is taken by the
QMC6310 magnetometer), but SH1106Display::begin() only tried 0x3C.
Initialize Wire for TBEAM_SUPREME_SX1262, and have SH1106Display::begin()
prefer 0x3D (only ever used by the OLED) before falling back to 0x3C.
Backwards-compatible for boards with the OLED at 0x3C.
Closes#2609
Added support for deferred OTA updates in the MyMesh class, allowing
the system to schedule firmware updates to occur after a confirmation
reply is sent. This change improves the user experience by ensuring
that the update process does not block the main application loop,
allowing for smoother operation during firmware updates.
Updated the startOTAUpdate method to serve the ElegantOTA on the
station IP when connected to a WiFi network, enhancing accessibility
for OTA updates. If not connected, it defaults to the MeshCore-OTA
SoftAP. This change improves the user experience by allowing easier
access to OTA updates without needing to switch networks.
Updated the otaFromManifest method to stream-parse the firmware manifest
directly from the network, reducing peak RAM usage during OTA checks. This
change enhances compatibility with slow TLS links by implementing a per-read
timeout, ensuring a more efficient and reliable update process.
Updated the otaFromManifest method to enforce HTTP/1.0 for better
compatibility with CDNs and to handle empty manifest responses. This
ensures that the JSON parser receives a complete body, preventing
errors during firmware update checks.
Added functionality to support pull-based OTA updates by fetching firmware
from a manifest. The new `otaFromManifest` method allows the system to
check for available updates and flash the firmware if necessary. This
enhancement improves the update process for observer builds using the
MQTT bridge, ensuring a more seamless firmware management experience.
Updated the build-observer-firmwares.yml to improve the asset pruning
logic during the release process. The workflow now retains the most
recent build hashes to prevent 404 errors for assets that may still
be requested during build cycles. This change ensures a smoother
release experience by maintaining necessary assets while cleaning
up older ones.
Updated the MQTTMessageBuilder to include microsecond precision in the
timestamp formatting. The formatIsoTimestampForMqtt function now accepts
a microsecond parameter, allowing for more accurate time representation.
Modified related functions in MQTTBridge to utilize the new timestamp
formatting, ensuring consistency across MQTT messages.
