How to control GPIO8 and GPIO9 of SX1302 as outputs? #7

I want to use SX1302 to operate LNA, I don't know how to do it? Only see the use of GPIO6. I did this without success： init / Select GPIO_8 to be controlled by HOST / lgw_reg_w(SX1302_REG_GPIO_GPIO_SEL_8_11_GPIO_8_SEL, 0); / Configure it as an OUTPUT / lgw_reg_w(SX1302_REG_GPIO_GPIO_DIR_L_DIRECTION, 0xFF);

/* Select GPIO_9 to be controlled by HOST */

lgw_reg_w(SX1302_REG_GPIO_GPIO_SEL_8_11_GPIO_11_9_SEL, 0); / Configure it as an OUTPUT / lgw_reg_w(SX1302_REG_GPIO_GPIO_DIR_L_DIRECTION, 0xFF);

out： //GPIO8 High lgw_reg_w(SX1302_REG_GPIO_GPIO_OUT_L_OUT_VALUE, 256); wait_ms(100); // GPIO8 low lgw_reg_w(SX1302_REG_GPIO_GPIO_OUT_L_OUT_VALUE, 0); //GPIO9 High lgw_reg_w(SX1302_REG_GPIO_GPIO_OUT_L_OUT_VALUE, 512); wait_ms(100); // GPIO9 low lgw_reg_w(SX1302_REG_GPIO_GPIO_OUT_L_OUT_VALUE, 0);
