* Introduce non-linear TX_GAIN_LORA
Previously, our TX_GAIN_LORA setting was a single number, intended
to represent the signal gain going through a power amp (plus or minus
antenna, attenuator, and other parts of the RF chain).
It turns out the relationship between the input power (i.e. from an SX1262)
and total output power is often non-linear. While we fudged a 1dBm difference
here and there with existing chips, the Heltec v4 has a 5dBm difference in gain
depending on which end of the input power (and frequency) you are at.
To allow people to run their Heltec v4 at max power when legal, and future
proof our code, this patch introduced an optional array-based TX_GAIN_LORA.
Define NUM_PA_POINTS and set TX_GAIN_LORA to gain values for a given input
power in 1dBm increments, and all will work.
For linear systems, just continue to define TX_GAIN_LORA as a number.
Fixes https://github.com/meshtastic/firmware/issues/8070
* Remove temporary power limit on heltec v4
* Add function RadioLibInterface::checkOutputPower
* Ensure SX126x reaches minimum supported power.
* Keep it simple, instead.
* Add seenRecently = true if wasUpgraded is true but unable to remove from queue (i.e. already sent/processed).
* Consistent comment between FloodingRouter and HopRouter
* If a packet is heard multiple times, rebroadcast using the highest hop limit
Sometimes a packet will be in the TX queue waiting to be transmitted,
when it is overheard being rebroadcast by another node, with a higher
hop limit remaining. When this occurs, modify the pending packet in
the TX queue to avoid unnecessarily wasting hops.
* Reprocess instead of modifying queued packet
In order to ensure that the traceroute module works correctly, rather
than modifying the hop limnit of the existing queued version of the
packet, simply drop it ifrom the queue and reprocess the version of the
packet with the superior hop limit.
* Update protobufs submodule
* Merge upstream/develop into overheard-hoptimisation branch
Resolved conflicts in:
- src/mesh/FloodingRouter.cpp: Integrated hop limit optimization with refactored duplicate handling
- src/mesh/MeshPacketQueue.h: Kept both hop_limit_lt parameter and new find() method
* Improve method naming and code clarity
- Rename findPacket() to getPacketFromQueue() for better clarity
- Make code DRY by having find() use getPacketFromQueue() internally
- Resolves method overloading conflict with clearer naming
* If a packet is heard multiple times, rebroadcast using the highest hop limit
Sometimes a packet will be in the TX queue waiting to be transmitted,
when it is overheard being rebroadcast by another node, with a higher
hop limit remaining. When this occurs, modify the pending packet in
the TX queue to avoid unnecessarily wasting hops.
* Improve router role checking using IS_ONE_OF macro
- Replace multiple individual role checks with cleaner IS_ONE_OF macro
- Add CLIENT_BASE support as suggested in PR #7992
- Include MeshTypes.h for IS_ONE_OF macro
- Makes code more maintainable and consistent with other parts of codebase
* Apply IS_ONE_OF improvement to NextHopRouter.cpp
- Replace multiple individual role checks with cleaner IS_ONE_OF macro
- Add CLIENT_BASE support for consistency
- Include MeshTypes.h for IS_ONE_OF macro
- Matches the pattern used in FloodingRouter.cpp
* Create and apply IS_ROUTER_ROLE() macro across codebase
- Add IS_ROUTER_ROLE() macro to meshUtils.h for consistent router role checking
- Update FloodingRouter.cpp to use macro in multiple locations
- Update NextHopRouter.cpp to use macro
- Include CLIENT_BASE role support
* Core Changes:
- Add hop_limit field to PacketRecord (17B→20B due to alignment)
- Extend wasSeenRecently() with wasUpgraded parameter
- Enable router optimization without duplicate app delivery
- Handle ROUTER_LATE delayed transmission properly
Technical Details:
- Memory overhead: ~4000 bytes for 1000 records
- Prevents duplicate message delivery while enabling routing optimization
- Maintains protocol integrity for ACK/NAK handling
- Supports upgrade from hop_limit=0 to hop_limit>0 scenarios
* Delete files accdentally added for merge
* Trunk formatting
* Packets are supposed to be unsigned. Thankfully, it's only a log message.
* Upgrade all packets, not just 0 hop packets.
* Not just unsigned, but hex. Updating packet log IDs.
* Fixed order of operations issue that prevented packetrs from being removed from the queue
* Fixing some bugs after testing. Only storing the maximum hop value in PacketRecord which makes sense. Also, updating messaging to make more sense in the logs.
* Fixed flow logic about how to handle re-inserting duplicate packets. Removed IS_ROUTER_ROLE macro and replaced it with better isRebroadcaster().
* Add logic to re-run modules, but avoid re-sending to phone.
* Refactor how to process the new packet with hops. Only update nodeDB and traceRouteModule.
* - Apply changes to both FloodingRouter and NextHopRouter classes to make packets mutable for traceroute
- MESHTASTIC_EXCLUDE_TRACEROUTE guard for when we don't want traceroute
* Allow MeshPacket to be modified in-place in processUpgradePacket
* let's not make a copy where a copy is unncessary.
