Hi Ryon,

There is a Readme.md file available under projects\dk_apps\demos\ble_multi_link SDK path. Please, check it and let me know if you need further clarifications on that.

Thanks, PM_Dialog

hi,PM_Dialog,

thank you for your reply.

yes,I know there is a Readme.md file available under there.But my question is when my board connect to the smartphone and other Slave device,how they send data to each other. .i.e.when connect to smartphone,smartphone send any data to my application by the serial port service? if so,when my device become main device to connect the slave device,how they communicate with each other.

thank you

Hi Ryon,

Can you please provide mores inputs on that? If I am understanding in correct, you are using the ble_multi_link with the DSPS reference application code? I you could provide more clarifications it would be very helpful.

Thanks, PM_Dialog

hi,

thanks for the reply.

In my project i need to send and receive data between DA14682 to DA14682. one of them run in central role and other one run in peripheral role.

and i know that I can use SPS profile to send and receive data between DA14682 to smartphone.but I dont know how to send and receive data betwwen da14682(run in centrral role) and da14682(run in peripheral role)

How can i do that, Please help me to do that.

Hi Ryon,

Thanks for your clarification. In this case, the usage of the ble_multi_link is not needed. You should only use the DSPS project. According to the user manual, the DSPS can be used to connect two DA1468x DKs or using a DA1468x DK and an Android / iOS device. The DA1468x DK can either function in the GAP central role or the peripheral role. The Android / iOS device only functions in the GAP central role. The application on the central device automatically connects to a peripheral device with the fixed BD address. Refer to theUM-B-084 : User Manual for Dialog Serial Port Profile (DA1468x)for getting more information. The DSPS include two projects:

v_1.160.2\projects\target_apps\ble_sps_central
v_1.160.2\projects\target_apps\ble_sps_peripheral

要做到这一点,在你的情况下,一个董事会should be programmed as a Central device and the other one as a Peripheral device. If you found the answer useful, please mark it as “accepted”.

Thanks, PM_Dialog

Sorry to reply so late

I have to clarify some thing

SDK:DA1468x_DA15xxx_SDK_1.0.14.1081

Demo: ble_multi_link

Device: DA14682

sorrry that I cannt find the DSPS project. And i know how to connect two DA1468x DKs or using a DA1468x DK and an Android / iOS device.

my question is how to communication. A DA1468x DK and an Android / iOS device can communication by using SPS profile,but I dont know that two DA1468x DKs use which profile to communicate.

thanks

Hi Ryon,

Here is the support portal for the DSPS and you can download the firmware for DA1468x product family.

//www.wsdof.com/products/dialog-serial-port-service-dsps

I would suggest you to read theUM-B-084 : User Manual for Dialog Serial Port Profile (DA1468x)as well.

Thanks, PM_Dialog
