how to develop an application to read current time characteristics from central device (ios app)

[sruthi.k.s]

Hi,

Tried to develop an application to read current time characteristics from central device (ios app) by using nrf51822 peripheral device(s110_nrf51822 v7.0.0.). After the setting of the discovered descriptor (p_service->time_stamp_char.handle_cccd = p_desc_resp->handle; p_service->time_stamp_char.des_uuid=p_desc_resp->uuid; ),tried to read characteristics by using sd_ble_gattc_read API. Got BLE_GATTC_EVT_READ_RSP.but there is no more data to read. Then tried by changing the handle of character value to handle of character declaration (msg->req.read_handle =m_service.time_stamp_char.handle_decl;). but got incorrect result....I have attached zipped file of the project with this. Would you test it there.. I am using nRF51822 Evaluation Kit(PCA10001) and keil compiler

So, if I understand you correctly, you want to connect your nRF51822 to an iOS device, and read out the current time information from the iOS device. The iOS device acts as a server, and the nRF51 as a client.

Can you please provide me details on how the iOS server is configured? I was able to compile and run your code, and discover the services on the nRF51822 from MCP. But I need to know how the iOS server is set up in order for the nRF51822 to discover the services.

Did you try to read characteristic by UUID? developer.nordicsemi.com/.../a00875.html

Hi Stian, I'm very interesting about this application (ble_cts client on nRF51822 and cts server on smart phone). So I ask to you if is there an app for android phone to implement this application and if Nordic has developed a ble_cts service (client) to put it in SDK (ble_services folder). Now I developed a cts service but I can not make it work. Thank, Paolo
