标题: 各位帮看看遇到一个棘手问题 1301 动态配置频段发现延迟...
由于客户要求将1301做成了  单信道  平台下发修改频段指令配置不同频段平台配置频段1301参数比较频繁代码在下面  遇到问题是每次重新配置必须要 lgwstop 然后再lgwstart 但是发现配置完后这个时间比较长要3秒左右由于我集中器配置完就马上抄表了这个3秒时间太长了  平台而且是每10秒就要配置一次频段参数导致时间大大拉长  而且我发现调用 lgwsop lgwstart 这组函数频繁的话会出现  如下错误我的整体配置代码在最下面有遇到过解决了这个问题的请指教
lgw_start:999: ERROR: Version of AGC firmware not expected, actual:2 expected:4
