For this value we should make a patch to https://github.com/meshtastic/protobufs

Thank you! I have approved and waiting for another collaborator to merge.

@SeeedZhangyh , the protobufs have been updated. You can probably update the submodule and the changes should disappear from this patch since they are already in the repository...

These GPIO numbers do not match with port/pin mapping 
No any of LR2021 DIO pins are defined as RF switch one(s) 
No QSPI flash memory anymore ? |

FYI, there was another radiolib patch for the LR2021 that went in yesterday:

Yes, a minor bug has been fixed. We will be using the latest dependency packages from now on. Thank you.

@SeeedZhangyh , firstly: thank you very much for adding LR2021 support! It's a big effort and we're super happy you've done it in a way that other devices can benefit. Very appreciated. If possible, I would like to split this PR into two PRs -
Simply because smaller pieces of code generally make it easier/faster for the meshtastic code reviewers to complete their work. It's just a style preference, but I think it will help get this support merged faster. If that is acceptable for you, let me know whether you might like to make the PRs, or whether you want me to try and manipulate git on your behalf :) |
Thanks for pointing it out, it was my oversight to modify the pin description.I will make changes in a later commit. Regarding the issue of using the LR2021 pins as an RF switch, we haven't used it yet. If it's needed in the future, or if others need to use it, they can modify it here to maintain compatibility. The QSPI flash memory is still retained in the hardware. Thank you again. |
Does the T1000-E-Pro flash use the same GPIOs as a regular T1000-E one ? Does Meshtastic LR2021 node receive LoRa signal from SX127x based nodes or |
The QSPI Flash pin assignments do not appear to have changed, though this still requires further verification. Regarding the issues concerning the SX127x, I am currently unable to provide a precise response. I sincerely apologize for the delay; We will get back to you in a few days. |
It would also be fine if you could handle this on my behalf. Thank you very much. |
Thanks' ! yes, I can see that most GPIOs associated with QSPI flash remain vacant in your P1.13 in T1000-E is in use as QSPI flash ENABLE signal (active HIGH).

Hmm, I am curious about this board, is it in relation to this one? https://www.seeedstudio.com/LR2021-LoRa-Plus-Evaluation-kit-868Mhz-EU-V2-0-p-6697.html |
Regarding the QSPI-related pins, the signal pins remain consistent with the Tracker-T1000-E; |
The board you mentioned utilizes the same LoRa module—the LR2021—as this board. |
|
Unlike regular T1000-E, the PRO has RTC, right ?

Thank you very much! |
Ah so this is a new product! Nice! Thanks for coming back to me 🙂 |

Pull request overview
Adds Meshtastic firmware support scaffolding for the Seeed SenseCAP Tracker T1000-E-Pro (nRF52840), including board/variant definitions and related platform integration.
Changes:
- Introduces a new nRF52840 variant folder for
tracker-t1000-e-pro(pins, peripherals, and PlatformIO env). - Extends deep-sleep handling to cover
TRACKER_T1000_E_PROand adjusts environmental telemetry sensor registration gating. - Updates the RadioLib dependency pin and adds the hardware model mapping in the nRF52 architecture layer.

custom_meshtastic_hw_model is set to 71 (same as TRACKER_T1000_E), but the protobuf hardware model enum for TRACKER_T1000_E_PRO is 128 (see src/mesh/generated/meshtastic/mesh.pb.h). This mismatch will cause incorrect hwModel metadata/identification for this target.
Update custom_meshtastic_hw_model to 128 to match meshtastic_HardwareModel_TRACKER_T1000_E_PRO and keep custom_meshtastic_hw_model_slug consistent.

Is there an actual or 3D rendered picture of how the Pro Tracker will look like ? |
Support for the T1000-E-Pro Development Board
Summary
Building upon the previous release, this PR extends support to the Pro version of the Tracker-T1000-E, incorporating the necessary hardware adaptations and software implementations.
Key updates in this release include: upgrading the LoRa module to the LR2021, maintaining support for existing GNSS functionality with enhanced dual-frequency positioning via the AG3335, and adding integrated support for the DRV2605 haptic feedback motor. The specific changes are detailed below:
Board Support: T1000-E-Pro
Added support for the T1000-E-Pro development board: New configuration files and associated settings specific to the T1000-E-Pro have been added to ensure full compatibility and proper operation within the Meshtastic ecosystem.
LoRa Module Update: LR2021
The LoRa subsystem has been updated to support the LR20x0 series modules. Since the Pro version utilizes the LR2021 to replace the LoRa hardware found in the previous iteration, this update introduces the corresponding software adaptations required to ensure the LR2021 module communicates correctly and functions properly on the T1000-E-Pro board.
GNSS Enhancement: AG3335 (Dual-Frequency Support)
While maintaining compatibility with the existing GPS framework, the Pro version leverages the AG3335’s dual-frequency capability to provide improved positioning accuracy and reliability.
This PR represents a further extension of the support provided in the previous release. While the current implementation may still contain areas open to optimization, the community is warmly invited to provide suggestions and feedback to assist in the ongoing refinement of these features.
Thank you for considering this PR and for any help or guidance you can provide.
Best regards,
