   ⚠️ Check that radio.rxgain(on) and flood.advert.base (0.308) are set correctly after flashing! ⚠️

   This build is based on official MeshCore 1.15.0 dev branch (as of 25-May-2026 and additionally includes the following unmerged upstream PRs/changes:

   • PR2553: Limit flood advert packet forwarding --> set flood.advert.base 0...1 (0: no flood adv. forwarding, 0.308: default, 1: all flood adv. forwarding)
   • PR1810: Allow direct message paths when denyf * is set
   • :new: PR1727: Use hardware channel activity detection for checking interference --> Use set int.thresh 1 to activate hw based channel activity detection.
   • :new: PR2377: Disable NRF52 undervoltage bootlock feature

   Additional changes:

   • Flood adverts are disabled (flood.advert.interval set to 0) by default
   • :new: modified PR1810 to not block flood adverts but only PAYLOAD_TYPE_GRP_TXT and PAYLOAD_TYPE_GRP_DATA so that some limited flood advert distribution can be managed via PR2553 to support e.g. observer maps.

   Changelog:

   • Based on dev v1.15.0 as of 25-May-2026

   ⚠️ Check that radio.rxgain(on) and flood.advert.base (0.308) are set correctly after flashing! ⚠️

   This build is based on official MeshCore 1.15.0 dev branch (as of 14-May-2026 and additionally includes the following unmerged upstream PRs/changes:

   • PR2553: Limit flood advert packet forwarding --> set flood.advert.base 0...1 (0: no flood adv. forwarding, 0.308: default, 1: all flood adv. forwarding)
   • PR1810: Allow direct message paths when denyf * is set
   • :new: PR1727: Use hardware channel activity detection for checking interference --> Use set int.thresh 1 to activate hw based channel activity detection.

   Additional changes:

   • RAK 4631, Xiao NRf, T114 variant: Lowered lockout voltage from 3.3V to 0V, preventing boards operated with different battery chemistries like LTO or LiFePo4 from booting. This is an issue e.g. if uart.cz boards are being used. (See discussion here.)
   • Flood adverts are disabled (flood.advert.interval set to 0) by default
   • :new: LORA_CR set to 8 as default in platformio.ini
   • :new: modified PR1810 to not block flood adverts but only PAYLOAD_TYPE_GRP_TXT and PAYLOAD_TYPE_GRP_DATA so that some limited flood advert distribution can be managed via PR2553 to support e.g. observer maps.
