S120 Scanner and S110 Peripheral Device pairing and exchange data.

[HakJae]

Hi, I have two device. S120 Scanner and S110 Peripheral Device. At Scanner, I use SDK 9.0.0 and S130 1.0.0, At Peripheral Device, I use SDK 9.0.0 and S110 8.0.0 ..

Scanner

• It is based "ble_app_uart_c_S120-master".
• I check pairing and exchange data with "NUS example code"

Peripheral Device

• It is based "ble_app_uart"
• I added some custom service, flash memory, dfu service.
• I check exchange data with Smartphone.

When i try to pair My Scanner and My Peripheral Device, At Scanner side, it repeat evt connect. At peripheral side, it is repeat "Connect evt - reset".

So i tried to do some case.

Scanner Side

• I adjust "device_manager_cnfg.h -> DEVICE_MANAGER_MAX_CONNEDCTIONS" 0 -> 8.

  -> It repeat "Connect - recieve data - Disconnect" a 6 times. After My peripheral device is not working.

Peripheral Side

• I try to delete dm_ble_evt_handler().

  -> It could pairing and exchange data, but it could't use DFU service.

In order to pairing and exchange data, What should i do ?

Please help me ..

Hi Hakjae,

Most likely there was an error thrown but not handled and trigger a reset in app_error_handler. What you can do is to run in debug mode and add a break point inside app_error_handler(). You may need to add DEBUG preprocessor symbol in the C/C++ project option. Inside that function, you should be able to find the file name and line number caused the issue.
