Update 20240612 - Example DMX Controller BLE Purpose To control DMX LED lights from a desktop application sending commands via Bluetooth Low Energy (BLE). Concept An ESP32-WROOM-32 (ESP32) runs a B4R program as the DMX BLE Controller (with identifier DMXBLECONTROLLER). The ESP32 waits for BLE clie

Thanks for the steer. Implemented serialized data, i.e. objects, sent from B4A to B4R via BLE = Working fine. The other way around, i.e. B4R to B4A using asyncstream write is also working =requires manager.setnotify. Background Working on a LEGO Showcase to remote control LEGO trains (via B4A) and

In case anyone got this far down without moving on in frustration... BLE = Bluetooth Low Energy, and requires some sort of (BLE) Shield.

You need to write the AT+DISI? command and then wait for incoming data. It requires some configuration. See the command description here: https://people.ece.cornell.%20TECH%20HM-10%20datasheet.pdf

FYI Based on the rLegoinoBoost library, developed a B4A Class to direct control, without the ESP32 B4R Bridge, the BoostRCCar via a B4A App using the BLE2 library. The B4A B4XPages app writes, after connecting, data direct to the hub via the BLEManager2 and handled hub response in the manager data a
