Internet access between WiFi-IoT in Access Point mode with mobile phone connected -

i did lot of brain-storming this, , couldn't reach solution.

i posting can ideas.

i have developed wifi-iot based device sensor, shows in ap mode. mobile phone connects ap , device starts sending sensor data mobile phone. mobile application plots , displays data.

now, want send data mobile internet. connecting mobile ap internet not option, don't want break continuous data transmission.

using internet of data provider 1 option, brings constraint of have mobile data.

what other options have send data mobile internet ??

edit:-

i worked on suggestions, , came point:-

1) wifi-iot device (in station mode) , mobile phone connect same internet-enabled wifi access point. wifi-iot device has ip address of mobile phone current network, , sends data tcp port (eg. 9801) of ip address. application in mobile phone reads data port no. 9801 , stores , hosts on internet.

this works fine.

2)wifi-iot device comes in access point mode, , mobile phone connects access point. there one-to-one connection between wifi-iot device , mobile phone.

my question is, in second scenario, without breaking one-to-one connection, there way host data internet:-

1) without using mobile internet provided mobile data service provider ?

2) without using second mobile phone ?

i may wrong, asking make sure whether requirement can achieved or not !!

i don't think can connect 2 aps @ same time.

maybe use bluetooth device phone link?

or have device connect directly internet after config done in ap mode , send copy of data phone app (either via wan or locally private ip phone gets internet gateway ap)?

--edit-- let me explain second one:

what mean have iot device directly connect internet , send data server (your phone has connected internet). make server send data copy phone. it's 2 step process: 1) while iot device in ap mode, use phone login , configure internet-connected ap should connected to. serves ui iot device. 2) start sending data.

or bit ugly, let iot device talk phone in same wifi network via private ip.

i brought way because mentioned anyway device has send data internet(i assume it's server) , have phone talk known location server more portable , scalable once have more 1 iot device.

--further edit-- don't think there way described. @ least experience:

1) on link layer, wireless nic has able connect 2 aps @ same time. not feature available. 2) on network layer, there has 2 ip address attached same nic, don't think available in current os wireless nics. though there way ethernet card, i.e. via aliasing.
