SimpleLink CC2640R2 SDK (4.20.00.04)这个版本已经不再支持AOA了？

CC2640最新的SDK中已经没有RTLS Toolbox的相关资料和文档了。相关的资料在SimpleLink™ CC13X2 / CC26X2 SDK.的SDK中有，AOA这部分功能已经转向CC26X2系列了？

那请问，我们买的CC2640R2的硬件套件，芯片换成CC2652，调试CC26X2的SDK？

请问，软件方面simplelink_cc13x2_26x2_sdk_4_30_00_54这个版本SDK中，rtls_master/rtls_passive项目中的关于天线切换部分代码找不到了。请问这部分是做了怎么样的修改
#define NUM_ENTRIES3
#define SWITCH_TIME2

#define ANT1(1<<28)
#define ANT2(1<<29)
#define ANT3(1<<30)
#define IO_MASK(ANT1 | ANT2 | ANT3)

uint32_t antSwitching[] =
{NUM_ENTRIES | (SWITCH_TIME << 8),IO_MASK,ANT1,ANT2,ANT3
};

在RTLS_CMD_AOA_SET_PARAMS中，在python中设置了天线切换模式

Listing 99. AoaSetParamsReq:

class AoaSetParamsReq(NpiRequest, SyncReq, FromAp):command = Commands.RTLS_CMD_AOA_SET_PARAMSstruct = Struct("aoaRole" / Enum(Int8ul, AoaRole),# AOA_MASTER, AOA_SLAVE, AOA_PASSIVE"aoaResultMode" / Enum(Int8ul, AoaResultMode),# AOA_MODE_ANGLE, AOA_MODE_PAIR_ANGLES, AOA_MODE_RAW"connHandle" / Int16ul,"slotDurations" / Int8ul,# 1us/2us sampling slots"sampleRate" / Int8ul,# 1Mhz (BT5.1 spec), 2Mhz, 3Mhz or 4Mhz - this enables oversampling"sampleSize" / Int8ul,# 8 bit sample (as defined by BT5.1 spec), 16 bit sample (higher accuracy)"sampleCtrl" / Int8ul,# sample control flags bit[0] = 0-default filtering, bit[0]= 1-RAW_RF no filtering# bit 4,5 - 0x10 - ONLY_ANT_1, 0x20 - ONLY_ANT_2# 0x00 is not a valid option."samplingEnable" / Int8ul,# 0 = mask CTE even if enabled, 1 = don't mask CTE, even if disabled (support Unrequested CTE)"numAnt" / Int8ul,# Number of antennas in antenna array"antArray" / Int8ul[this.numAnt],# GPIO's of antennas)

谢谢，这部分已经看到了。还需要请教一个新的问题，自己设置了圆形阵列的天线，需要通过8个GPIO去控制更多的12个天线切换两遍。控制的GPIO我需要修改的python和rtls_master中的哪些部分？  

python中

                    "aoa_cc26x2": {
                        "aoa_slot_durations": 1,
                        "aoa_sample_rate": 1,
                        "aoa_sample_size": 1,
                        "aoa_sampling_control": int('0x10', 16),
                        ## bit 0   – 0x00 – default filtering, 0x01 – RAW_RF no filtering,
                        ## bit 4,5 – default: 0x10 – ONLY_ANT_1, optional: 0x20 – ONLY_ANT_2
                        "aoa_sampling_enable": 1,
                        "aoa_pattern_len": 24,
                        "aoa_ant_pattern": [0, 1, 2,3,4,5,6,7,8,9,10,11，0, 1, 2,3,4,5,6,7,8,9,10,11]
                    }

rtls_master的AOA.C中

void AOA_init(uint8_t startAntenna){#ifdef RTLS_PASSIVE                //此处宏定义passive有效的话， 在只用master的作为测量设备，需要在配置引脚切换。 uint8_t antArray[BOOSTXL_AOA_NUM_ANT + 1] = {ANT2, ANT1, ANT3, ANT4, ANT5, ANT6, ANT7,ANT8, ANT9, ANT10, ANT11, ANT12,ANT2, ANT1, ANT3, ANT4, ANT5, ANT6, ANT7,ANT8, ANT9, ANT10, ANT11, ANT12, ANT_ARRAY};

// Init only once if (gPinHandle == NULL) { AOA_initAntArray(antArray, BOOSTXL_AOA_NUM_ANT + 1); }

// Initialize ant array switch pin if (startAntenna == 2) { // Start with A2 (ANT_ARRAY pin high is A1, low is A2) PINCC26XX_setOutputValue(ANT_ARRAY, 0); } else { // Start with A1 (ANT_ARRAY pin high is A1, low is A2) PINCC26XX_setOutputValue(ANT_ARRAY, 1); }#endif

另外，如果天线数量增加，这个结构体数组需不需要增加。
AoA_AntennaPair_t pair_A1[] =
{{// v12.a = 0,// First antenna in pair.b = 1,// Second antenna in pair.sign = 1,// Sign for the result.offset = 10, // Measurement offset compensation.gain = 0.95, // Measurement gain compensation},{// v23.a = 1,.b = 2,.sign = 1,.offset = -5,.gain = 0.9,},{// v13.a = 0,.b = 2,.sign = 1,.offset = -20,.gain = 0.50,},
};
