Hi.

Why do you want to slow down the update speed?

You cant change anything in the secure_bootloader example, this example only updates the Application (or Application and SoftDevice, or Application and SoftDevice and Bootloader).

You have to increase the connection parameters on the device you are sending from(MIN_CONN_INTERVAL and MAX_CONN_INTERVAL in main.c). You can also decrease the event length size (NRF_SDH_BLE_GAP_EVENT_LENGTH in sdk_config.h)

Best regards,

Hi. I found when the DFU speed is so fast that the update process disconnect.when i slow down the speed is ok. i use the huawei mobile phone

Hi.

The disconnect reason must be something else.

As I said in my previous reply, you need to change the connection parameters on the device you are sending from. So you need to find out how to do that on the Huawei phone you have.

Best regards,
