central and peripheral multilink problem

[ariestian]

hi Nordic engineer

hard platform : N53832DK, 51822DK

software platform nRF52832 use SDK_14.2.0, nRF51822 use SDK 12.3.0

nRF52832 as ecntral and peripheral; nRF51822 as peripheral.

I 'm  using the ble_app_multilink_central demo to achieve central and peripheral multilink. now base function has achieved. However, some problems cannot be solved,

when more than one peripherals(nRF51822) connected with central(nRF52832)  and then some peripheral disconnected. when online peripheral send data to central will issue error.

for example : 3 peripherals and 1 central online then 1 peripheral offline, 1 peripheral send "nRF51822" . central log out  two times "nRF51822"

if 2 peripheral offline, 1peripheral send "nRF51822". central log out three times "nRF51822". 

if all peripheral online all devices working good.

i'm sure peripheral just send data once.

thanks very much

Hi,

I'm not sure if I understood all this.

1. when online peripheral send data to central will issue error.
   What does this error say specifically?
2. 1 peripheral send "nRF51822": 
   What do you mean by "send nRF51822"?
3. Are you using an example from the SDK on your nRF51 peripherals too? If so, then which one?
   
   
4. Is it possible for you to upload your project files?

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 ?

Hi ariestian,

Did you get solution for the conn_handle has changed, I got same problem but until not get solution. Please can you help me if you get solution.

Thanks,,,,,
