【Qinheng RISC-V core CH582】Upgrade program via Bluetooth [Copy link]

 

 

First download the program CH582\EVT\EXAM\BLE\BackupUpgrade_OTA to the development board

Then send the CH583 upgrade tool to the phone, with an additional suffix 1. Select the installer to open. The installation process requires reading the camera information, which I refuse.

It prompted me to get the address information again, and I refused again. Then, the Bluetooth program prompted that it could not run, but it did not exit.

But when I scanned the Bluetooth device, it prompted me to turn on the location information.

Do you collect my location information? I hate this. Just agree to it, otherwise I can't use it.

After authorizing the storage and location information, I opened the upgrade tool and it automatically started scanning for Bluetooth devices. However, no Bluetooth devices were found in the end. Is it because my development board program is wrong?

Select the installer to open. The installation process requires reading camera information. Reject.

Prompt to obtain address information, but refuse

Is this the problem?

No, I authorized them later, and now I can search for a smart watch, but it cannot connect to it. It is definitely not the Bluetooth of the development board.

For Android phones, Bluetooth authorization requires authorization of location information. I have checked this issue before.

To use Bluetooth, you must obtain positioning information, which is a necessary permission to use the Bluetooth function.

The Bluetooth of the development board has a name:

// GAP GATT Attributes
static uint8_t attDeviceName[GAP_DEVICE_NAME_LEN] = "LuglBLE";

static uint8_t scanRspData[] = {
// complete name
0x8, // length of this data
GAP_ADTYPE_LOCAL_NAME_COMPLETE,
'L',
'u',
'g',
'l',
'B',
'L',
'E',

You can change these two places to your own name. Then you won't go wrong.

There is a name in the program, and the name is correct, but it is not linked to the upgraded APP. I don’t know why

Did I burn the wrong firmware? Generally speaking, this shouldn't cause any problems. I haven't learned that lesson yet.

It's possible. The information didn't say which one can be used. I tried them one by one. I burned the serial port to the program. I thought there was a problem. It turned out to be a long process. After 137 seconds, the serial port download was finally successful.

Download a normal peripheral program first to see if the phone can connect

Thanks, I'm busy these days.

I'll download a broadcast and try it out

kangkls

This is also considered a successful link.

But burn EVT\EXAM\BLE\BackupUpgrade_OTA\BackupUpgrade_OTA.hex

After that, the mobile phone Bluetooth still cannot search for Bluetooth devices

Broadcast is a one-way broadcast that does not establish a connection, but at least proves that communication in one direction is successful.
