I2C: Intentando leer múltiples registros, repitiendo primero el primer registro

Estoy intentando leer los registros 0x28 a 0x2D de la L3G4200D (giroscopio, hoja de datos ), que es parte de la placa GY-80, usando el esp32 ( I2C info ) como maestro, que forma parte de la placa LOLIN32. Pero en vez de eso, el primer byte se repite ocho veces y no puedo entender por qué. Obtengo el resultado correcto cuando leo los registros uno por uno.

Los registros se encuentran en la hoja de datos aquí:

Este es el paquete I2C visto a través de mi osciloscopio (picoscope):

Estoy usando este código para enviar el paquete:

 
//I2C init:

  conf.scl_io_num = GPIO_NUM_17;
  conf.scl_pullup_en = GPIO_PULLUP_ENABLE;
  conf.master.clk_speed = 400000;
  i2c_param_config(I2C_NUM_0, &conf);
  i2c_driver_install(I2C_NUM_0, conf.mode, 0, 0, 0);
