/**
 * HM-10 (and compatible CC2540/CC2541 modules: HM-11, AT-09, JDY-08, …)
 * transparent-serial profile.
 *
 * Unlike Nordic UART's two-characteristic design, the HM-10 multiplexes both
 * directions onto a *single* characteristic `0000ffe1-…` on service
 * `0000ffe0-…`: the host writes to it (write-without-response) and the device
 * pushes inbound bytes back via notifications on the very same handle.
 *
 * Strictly W3C `navigator.bluetooth` GATT: notifications are enabled through
 * {@link BaseProfile.subscribe} (`startNotifications()`); this profile never
 * reads or writes a CCCD/SCCD descriptor itself.
 *
 * @example
 * ```ts
 * import { HM10SerialProfile } from '@beacio/core/profiles';
 *
 * // requestDevice({ filters: [{ services: ['0000ffe0-0000-1000-8000-00805f9b34fb'] }] })
 * const serial = new HM10SerialProfile(device);
 * await serial.connect();
 *
 * const decoder = new TextDecoder();
 * const unsubscribe = serial.onReceive((chunk) => {
 *   console.log(decoder.decode(chunk));
 * });
 *
 * await serial.send(new TextEncoder().encode('AT+NAME?\r\n'));
 *
 * unsubscribe();
 * serial.stop();
 * ```
