Как расширить возможное количество сервисов BLE на ESP32

0 голосов
/ 25 января 2020

Я пытаюсь предоставить около 18 различных сервисов на одном BLE-устройстве. Устройство, которое я выбрал, - ESP32. Если я попробую следующий код в Arduino-IDE, код остановится (больше не будет операторов в последовательном мониторе) после запуска 7 сервисов.

Ограничено ли количество возможных BLE-сервисов на ESP32 или может Я что-то изменил в коде, чтобы расширить число?

Заранее спасибо
