ECG plot using PCA10004/5

[Shrijit Mukherjee]

Hi, I was wondering if anyone has done this seemingly doable job of producing continuous ECG trace using PCA1004 and PCA10005 devices. My intended use case is this: Use one of PCA10004 or PCA10005 as Master and other as slave (GATT server and client). Use the Analogue input of the slave to connect to a ECG simulator (www.ms-gmbh.de/.../phantom_start.htm) and transmit data continuously to a PC , connected with the other device. Or, the PC may be connected to PCA10000 dongle as GATT client.

It may also be fine to use only one of the boards to transmit data (GATT server) and see it on a iOS device.

Has anyone done a similar task?

I see this post to be closely relevant but doesn't end successfully.

I'd strongly recommend you to take a look at nAN-36 and the accompanying code on GitHub. This shows how to build a custom service and send data.

You may also have use in looking at ble_app_hrs in the SDK, which shows how you can send heart rate data, using the standard Bluetooth SIG heart rate service.

Also, the User Guide for your kit shows how to just test the ready-made application, which may be useful to get a feel for how this works.
