How to change my NUS_BASE_UUID

[role_2099]

I want to modify the uuid through the serial port. What variables can I use to describe this define? Is there any code for reference?

#define BLE_UUID_NUS_TX_CHARACTERISTIC 0x0003               /**< The UUID of the TX Characteristic. */
#define BLE_UUID_NUS_RX_CHARACTERISTIC 0x0002               /**< The UUID of the RX Characteristic. */
#define NUS_BASE_UUID                  {{0x9E, 0xCA, 0xDC, 0x24, 0x0E, 0xE5, 0xA9, 0xE0, 0x93, 0xF3, 0x27, 0x05, 0x00, 0x00, 0x40, 0x6E}} /**< Used vendor specific UUID. */

Best wishes and regards!

John

Why do you want to change it?

I'm not sure that the nRF5 SDK supports dynamically changing services at runtime?

This tutorial series explains about custom Characteristics and Services in the nRF5 SDK:

just find where they are used in the code - and change that to use something else.

But, again, I'm not sure that the nRF5 SDK supports dynamically changing services at runtime?

Hi awneil,

Thank you for your reply. Let me take a look at the two links you sent. I just tried to modify BLE_UUID_NUS_SERVICE, but they all failed. It prompted him to be a constant and cannot be changed to a variable.

Still leaves the question of why you want to do this?
