where do we receive the battery value in s130,ble_central_and_peripheral

[deepu]

The codes i am using is nRF51_SDK_8.1.0_b6ed55fnnn\examples\ble_central_and_peripheral and nRF51_SDK_8.1.0_b6ed55fnnn\examples\ble_peripheral\ble_app_hrs

From the peripheral, it sends heart rate value and battery value over bluetooth.We receive the heart rate value in ble_evt_t.evt.gattc_evt.params.hvx.data[1] at the other side ie, in the 1st code But i can't find the variable in which we receive the battery value in the 1st code.surely there must be a variable.do anyone know it??

please help

@deepu: In the ble_central_and_peripheral () we don't look for the battery service and only forcus on the heart rate measurement service as you can find in discovery() function in main.c.

It's only an experimental project, so it's pretty modest. You would need to add the code to scan for Battery service UUID, look for the CCCD and enable it to be able to receive notification for battery.

I would also suggest you to use the device_manager_central and ble_db_discovery.c library as we used in the S120 example (ble_central) to do the task.

ty hung,

where do we receive the slave address and name in ble_central_and_peripheral so that,we can connect even to an unknown slave by giving the received address rather than giving the address in the beginning

@deepu: You can do a scanning. And when you capture an advertising packet, you will receive a BLE_GAP_EVT_ADV_REPORT event. In that event you can find the address, advertising data. Please have a look at the ble_app_hrs_c project in ble_central folder.
