I have application that ble_module_dual .

[EdwardLeung]

using S130, SDK11,

when it connected the heart rate sensor A and eveything is OK.

but when it disconnected the sensor A and connected the sensor B

the connecting is OK but no notification was not happened.

The sensor A and sensor B are difference device name.

WHY ?

[Petter Myhre]

So you have two nRF devices? Running ble_app_hrs? With different device name? You connect them to what?

[EdwardLeung]

1. NOT ruuning ble_app_hrs

2. running ble_module_dual ( central and peripheral ) .

3. we have two heart rate sensor which have the different device name

4. when connected the heart rate sensor A and notification is OK.

5. but when it disconnected the sensor A and connected the sensor B

6. the connecting is OK but no notification was not happened.

[Petter Myhre]

ble_module_dual? That is not an example in our SDK. So you have a two commerical heart rate sensors? And you want to connect them to a nrf running S130. Could you elaborate on what this ble_module_dual firmware is doing? Maybe you can edit your question and include some code? Or maybe you complete project? We have no idea what you are doing.

[EdwardLeung]

NO it is an example in your SDK

the path is ...nRF51_SDK_11.0.0>examples>ble_central_and_peripheral>experimental>ble_module_dual

[Petter Myhre]

It is not. There are two examples in \examples\ble_central_and_peripheral\experimental:

ble_app_hrs_rscs_relay and ble_app_multirole_lesc. Do you mean ble_app_hrs_rscs_relay?
