From fe7c15d0b92f596da233835453a402a89d3f6882 Mon Sep 17 00:00:00 2001 From: Patrick Schurig Date: Wed, 24 Jun 2026 23:33:15 +0200 Subject: [PATCH] abbterra: split status block to respect 31-byte RT38B01 frame limit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The status block (12 registers × 2 words = 24 words) was read as a single Modbus request, producing a 53-byte response that overflows the RT38B01 433 MHz radio module's 31-byte frame limit. Dissolve the status block into individual registers with readSchedule:update so queuedRequests sends them one at a time (max 9 bytes per response). The deviceInfo init block (8 words → 21 bytes) is left untouched. Bump to 1.15.0+etm6.
