工程师,你好!
参考了之前提供的信息:https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/p/628551/2363574?tisearch=e2e-sitesearch&keymatch=CC1310%204FSK#2363574
目前CC1310可以 4FSK 1Mbps进行收发,但我尝试修改RF_cmdPropRadioDivSetup_4fsk.txPower的值来调整发射功率时,却没变化。
请问其发射功率是否可调呢?要如何计算配参?
谢谢!
Viki Shi:
你目前的TX power是多少?准备调整到多少?

目前的配置参数是:
rfc_CMD_PROP_RADIO_DIV_SETUP_t RF_cmdPropRadioDivSetup_4fsk ={ .commandNo = 0x3807, .status = 0x0000, .pNextOp = 0, // INSERT APPLICABLE POINTER: (uint8_t*)&xxx .startTime = 0x00000000, .startTrigger.triggerType = 0x0, .startTrigger.bEnaCmd = 0x0, .startTrigger.triggerNo = 0x0, .startTrigger.pastTrig = 0x0, .condition.rule = 0x1, .condition.nSkip = 0x0, .modulation.modType = 0x1, .modulation.deviation = 400, .symbolRate.preScale = 0xF, .symbolRate.rateWord = 327680, //500k(1Mbps): 327680; 750k(1.5Mbps): 491520 NG; .rxBw = 47, //47, .preamConf.nPreamBytes = 0x6, .preamConf.preamMode = 0x1, .formatConf.nSwBits = 0x20, .formatConf.bBitReversal = 0x0, .formatConf.bMsbFirst = 0x1, .formatConf.fecMode = 9, // 4-ary .formatConf.whitenMode = 0x0, .config.frontEndMode = 0x0, .config.biasMode = 0x1, .config.bNoFsPowerUp = 0x0, .txPower = 0x3f, // default: 0x3f .pRegOverride = pOverrides_hs_4fsk, .centerFreq = 433, .intFreq = 0x0A66, .loDivider = 0x0A,};
基于rfPacketErrorRate工程进行移植,直连时的RSSI是-6dB;
想要测试0dB,10dB以及最高发射功率。
谢谢!

经了解,此模式的例程暂时没有官方正式发布,换言之,还是测试版,其他参数的设置建议在链接原帖,发个关联问题进行咨询
