nRF52832 extended advertising packet and extended data packet to send 1000kbyte data to ble uart

Sunil vignesh

Hi,

    I have a problem on two things

   1. I want to advertise my custom 128bit UUID with ble appearance and manufacturer data but when i did my advertising device name become shorten because or advertising packet length is up to 31 bytes . how to extended the advertising packet length 

2.  BLE UART example i can't able to send more than 27bytes . how to send more than that and how to enable ATT_MTU to send more length

I want to send the Analog sample to phone via NUS services. the array of samples be like 50KBytes sample i need to send at a stretch . is that possible to send that much data in a stretch

    Hi Sunil

    1. I'm not sure that extended advertising packets are the way to go if you only want to advertise the full 128bit UUID along with the existing advertising packet. I would recommend adding the 128bit UUID in as part of your scan response packet instead and implement a scan response to your advertisements.

    How to do this is described in this tutorial, and you can also check out I.E. ble_app_blinky example, where the scan response is used.

    Best regards,

    Simon
