Estaba buscando la posibilidad de escanear un gran número de etiquetas BLE (StickNFind) en un solo escaneo. Me he dado cuenta de que cuando escaneo durante 10 segundos puedo detectar alrededor de 20 BLE fácilmente. Cuando aumente el intervalo de escaneo a alrededor de 30 segundos e intento escanear una gran cantidad de etiquetas BLE, por ejemplo. 200 etiquetas, veo un error en el LogCat sobre desbordamiento de búfer (GKI_exception). Este problema ocurre en algún lugar de las bibliotecas básicas de Android, que no puedo depurar. Se adjunta el registro de error exacto.
