Re: Power consumption problem when the AP is not avaliable

Hi, we've tried all related APIs, but no lucky, ESP8266 consumed too much battery when AP is not exist, are you still working with this problem? Glad to hear from you, thanks! hi, Harold L We have a lower power working mode ,base on deep sleep mode. please give your e-mail address to me, we will co...

Re: RTOS版本v1.0.4版本,sniffer模式下,为什么模块在channel6也能收到channel11的数据?

按照道理,不至于信道差距这么大还能收到相关数据。


sniffer 在相邻信道收到信号是正常现象,这与手机与路由之间通信信号有关。
您可以这个处理:
1、对比信号强度,在CH11收到的包的信号强度会明显高于在相邻信道的收到的包的信号强度。
2、可以通过 wifi_station_scan 函数获取路由器所在的CH

Re: Power consumption problem when the AP is not avaliable

Thanks for your reply! Yes, we have very strong demand, because we're designing a hand-held device powered by battery, and customers need to have a longer battery life outside(e.g. on the streets, parks, restaurants...). Our device will upload datas through WIFI only after they coming back to home....

Re: Power consumption problem when the AP is not avaliable

Btw, you should focus on the relative value, the rising-edge of the current when power off your router(130mA - 70mA = 60mA) instead of the absolute values, because there exists some bias-current caused by things like LCD screen, external ADCs in my measurement. Surely, those things would not be the...

Re: Power consumption problem when the AP is not avaliable

Hi! We are designing a battery powered device on the top of ESP8266, and found there is abnormal high current during some situation. Firstly set ESP8266 to station mode. The total current was 70mA . Once in a while went up to 100mA , it's OK! But in both situations below, the total current went up ...

Re: EspTouch for IOS V3.0配置不了8266

关于烧录 ligth iot demo 配置乱码的问题。请确保在smartconfig过程中不能有操作flash的动作。 ligth iot里面好像有,请先屏蔽掉

Re: ESP8266连接流程疑问

问题1:芯片在返回了bssid和ip等信息之后,还会不会保持这个连接呢,会不会在返回这些信息之后就把连接关闭了? --->>设备端在给APP返回信息完成后,会把连接关闭。设备端发送的是UDP单播包。 问题2:手机连上了路由器,并通过smartconfig方式配置芯片连接上了同一个路由器,此时如果手机切换到另一个网络,然后再切换回来(与芯片在同一个路由器中),app与芯片之间要如何操作才能快速的找到对方呢,是通过约定端口,然后其中一方遍历ip吗? --->>因为APP端在连接完成后会返回设备的IP,如果手机去连接其他路由器在切换回来后,设备在路由上分配的ip不变的,APP端也可以根据此IP找到设备

Re: [ESP Smart Config] Adding other functions after Smart Co

hi, ESP8266 in smartconfig-ing, the Station mode and SoftAP mode should be closed. so the network connection could't work. if you want to run other function, may be after smartconfig_stop() case SC_STATUS_LINK_OVER: os_printf("SC_STATUS_LINK_OVER\n"); if (SC_Type == SC_TYPE_ESPTOUCH) { uin...
