How many devices can work with NRF52832 in the same time ?

[Michael.lee]

Hi  

I have a project which is using 53832 as the master ,  main 52832 works with smart phone by bluetooth ,and broadcasts ebike information throght the ANT+ .

I would like to add wireless button to this system.  so that main 52832 can change the working  mode / behavior according to the wireless button click.

do you think this can works ? 

If yes , is there any information i can refer ? 

Thank you in advance for your help.

I guess the closest example we have may be:

I believe your setup should work.

Yes, I know this S332 software device , in fact ,I have applied it into my previous project . it worked well with both LEV and  BlueTooth (Smart APP),  now ,I just want to add 2 more wireless buttons to it ,so the rider can changes assistant level through Bluetooth . What is your comments on this purpose ?

Do you want to create a new BLE link for these buttons or do you just want to add another BLE service&characteristic using the current BLE link for the buttons?

Hi Kenneth

I am not so sure, Since i am not so good at BLE connection .

I think new BLE link sounds good , but is it stable enought ,as you konw ,we donot want lost connection when riding ,we also think response quickly is necessary. 

Thank you for your advise.

In general the internal scheduler in the softdevice will give links that have slower connection intervals higher priority than those links with fast interval. That way, only the link with fast interval will be interrupted/skipped to ensure those links with slow interval can communicate. So I recommend that if you add a new link, then the interval should be faster than the other links. This should reduce risk of affecting existing links.
