NodePrefs::gps_interval has been persisted in the prefs blob (and the "gps.int" key) since it was added, but nothing outside companion_radio's CMD_SET_CUSTOM_VAR path could write it: CommonCLI's get/set commands are a hand-written chain that never reaches the ConfigSerializer tree, and simple_repeater's applyGpsPrefs() pushed only "gps" to the sensor manager and never the interval. The stored value was loaded, saved, and ignored, leaving EnvironmentSensorManager on its 1 s default -- which on a node with a fix prints two lat/lon debug lines per second. Add "gps interval [seconds]" in the shape of "gps advert": the bare form reports, the argument form applies and persists, capped at 24 hours, with zero keeping the firmware default of 1 s at both ends. The argument must be all digits, since _atoi() reads a typo like "abc" as 0 and would silently reset the pref while answering "ok". The prefix match requires a delimiter after "interval": memcmp(command, "gps interval", 12) matches "gps intervalX" too, which would then read its argument from past the 'X' -- an empty string, so 0 -- instead of falling through to the generic "gps" handler and being rejected. Trailing spaces read as the bare query. Teach simple_repeater's applyGpsPrefs() to re-apply a non-zero stored interval at boot, matching what companion_radio already does. simple_room_server and simple_sensor have the same gap in their own applyGpsPrefs() and are left alone here. gps_interval stays settable-but-not-enumerated in EnvironmentSensorManager, and the comment there records why: the enumeration calls also build RESP_CODE_CUSTOM_VARS's wire payload on every companion build, so listing it would change what every embedded companion node sends. It is also deliberately not gated on gps_detected, because every example's applyGpsPrefs() calls it at boot regardless. Documented in docs/cli_commands.md.

Summary
Adds a
gps interval [seconds]command toCommonCLI, and makes the repeater re-apply the persisted interval at boot.NodePrefs::gps_intervalalready existed and was serialised (gps.int), andEnvironmentSensorManageralready honoured agps_intervalsetting, but nothing outside the companion app'sCMD_SET_CUSTOM_VARpath could set it, andsimple_repeater'sapplyGpsPrefs()never pushed the stored value back to the sensor manager after a reboot.What changed
src/helpers/CommonCLI.cpp:gps intervalreports the stored value;gps interval <n>sets it (0–86400 s, 0 = firmware default of 1 s), forwards it to the sensor manager and saves prefs. The argument must be all digits —_atoi()reads a typo likeabcas 0, which would silently reset the pref instead of reporting the mistake. The prefix match checks for a delimiter afterinterval, otherwisegps intervalXwould parse past theXas its argument instead of falling through to the genericgpshandler and being rejected.examples/simple_repeater/MyMesh.h:applyGpsPrefs()applies a non-zero stored interval at boot, matchingcompanion_radio.src/helpers/sensors/EnvironmentSensorManager.cpp: comment recording whygps_intervalis deliberately settable-but-not-enumerated (enumerating it would changeCMD_GET_CUSTOM_VARS's wire payload on every companion build) and not gated ongps_detected(every example'sapplyGpsPrefs()calls it at boot regardless).docs/cli_commands.md: documents the command.At the 1 s default the two
lat …debug lines printed on every read dominate a debug log on a node with a fix; this is the knob for that too.How it was tested
pio test -e nativepasses (on macOS this needs the<stdlib.h>include from the small-fixes PR to compile at all; the suite is otherwise unaffected by this change).WioTrackerL1_repeater(nRF52) andheltec_tracker_v2_repeater(ESP32-S3).Dependencies
Independent. Applies to
dev. (Touches thegpshandler region ofCommonCLI.cppa few lines away from the NULL-check fix in the small-fixes PR; both apply cleanly in either order.)
