器件型号：CC1312R 大家好、
我有具有 cc1312R 的定制板。 目前、当每5秒发送792字节数据时、我的电路板消耗20mA 电流。 但20mA 对于我的应用而言过高。 我想将其降低至10mA 或更小。 您可以在下面看到射频设置和代码。
我将更改 TX 功率、例如12.5或12、电流将降低约17.5mA。 但这对我来说还不够。 在以11或10更改 txpower 后、9射频流耗以某种方式增加。 无论如何，我不想降低太多的 Txpower。 因为我需要在50-100米左右发送数据。 如果我对 TX 功率进行降级、距离范围将减小。
如何在不对 TX 功率进行过多去折痕的情况下对该电流进行去折痕？
缓冲区大小约为782字节。 更改尺寸对于当前组合很有用。
或者每秒发送一次是否合乎逻辑。(但发送时间可能会导致过多电流？)
另一个问题是数据发送时间大约为130-140毫秒。 这是正常的吗？ 如何缩短此时间？
