How to receive Image data on nrf51822

[sachin.singh]

Hi,

I am developing one of the application using nrf51822 with SDK S110. in which I need to receive the long data(like image) through the mobile app.

And newbie to the nrf51 development zone and I have gone through some example provided in the SDK S110. 

So, I need to receive the long data on nrf51822 via mobile.

Looking forward for the possible solution for the same ...

Thanks

Hi,

You will need to split the data into multiple smaller packets. The default packet payload in BLE is 20 bytes. I think the ble_app_uart example can be a good starting point for this.  Data sent from the phone will be forwarded to the nus_data_handler() in this example. 

Also, since you are using the s110 stack, please have a look at this blog post here, you may be impacted by the deprecation of BLE v.4.0 and v.4.1: https://devzone.nordicsemi.com/b/blog/posts/what-impact-does-the-deprecation-and-withdrawal-of-bluetooth-core-specification-v4-0-and-v4-1-have-on-your-current-and-future-products
