how to connect dual mode bluetooth use nrf52832, and get data through enable notyify?

[Diiiiiii]

Now i want use a device with dual mode bluetooth as peripheral, as manufactor says, the device auto select SPP or BLE through central who connected it. The data are subcontracted.

First i use "Nordic Connect (Android)"  connected the device, i can get some incomplete data after enable notify.

second, i use "Nordic Connect (iOS)" as like as first step, but i can get complete and corrent data.

then ,i modify the example "ble_app_hrs_rscs_relay--pca10040 " in "nRF5_SDK_14.0.0_3bcc1f7"  to connect the device with dual mode bluetooth. The reality is that ，after connect the device and enable notify, i get some incomplete data like use "Nordic Connect (Android)" .

is there anything i haven't done?

Hi. 

As you are referring to SPP and BLE I assume you want a solution where you want to use both BLE and BT Classic. 

I'm afraid that Nordic only supports BLE and not BT Classic, nor do we have any combo chip that supports both.

NO NO NO,i need BLE only, nrf52832 is necessary，i want connect the dual mode device by using 52832(BLE).

As mentioned above, Nordic Connect (iOS) can get complete and corrent data,can not 52832? if YES, it means Nordic Connect (iOS) support SPP?

If you have a dual mode device, you should be able to connect to a nRF52832 using BLE, but not  BT Classic. 

The nRF Connect (iOS) app only supports Bluetoot Low Energy services.
