maybe I find the reason resulting in my device work wrong, My connection handle has changed in the picture below.

the Connection handle has changed from 0x1 to 0x2000

could you give me some suggestion to solve this question ?

1. peripheral send a data central print out two data

2. send "nRF51822" string

3. nRF51822 used bl _peripheral ble_app_uart demo ; nRF52832 used ble_app_multilink_central demo and this project LBS_C service I have changed to NUS_C serivce.

I met the same issue.

The situation step is,

1. Two peripheral connected with central

2. Two peripheral disconnected with central

3. If just one peripheral connect with central, and this peripheral send data to central, then central will get BLE_GATTC_EVT_HVX event twice, that means central got two package data, the same data. But peripheral was just send once.

4. If the other peripheral connect, central will be ok.

Hi,

I'm not sure if I understood all this.

when online peripheral send data to central will issue error.
What does this error say specifically?
1 peripheral send "nRF51822":
What do you mean by "send nRF51822"?
Are you using an example from the SDK on your nRF51 peripherals too? If so, then which one?
Is it possible for you to upload your project files?
