Maximum Pairing and bonding data storage for DA14583

Hi karanshah28,

Yes, you could change the APP_BOND_DB_MAX_BONDED_PEERS, but could you please indicate which is the maximum number of bonded peers that you would like?

Thanks, PM_Dialog

Hi karanshah28,
The APP_BOND_DB_MAX_BONDED_PEERS is to set the number of available paired slots that the device will keep, so if for example you have set it to 5 that means that device will keep 5 slot for pairing information, in case there is a new connection and a new security request the device will overwrite that paired device and will store the new data in that slot. To be honest, we haven’t tested it with 100 devices, but I think that with 100 devices you will have memory leakage

Hi karanshah28,

I have to ask the Team internally for both your questions, so I will get back to you as soon as I have a feedback.

Thanks, PM_Dialog

Hi karanshah28,

Please check below the feedback I got from the Team regarding your queries.

1. 我们正在寻找100 devices to bond and pair. What is the maximum number of devices that can be bonded in DA14583 ?

Storing the maximum number of pairing and bonding data depends on several factors, such as -

1. Where would the application store bonding information (e.g Flash memory)

2. What kind of use case you are targeting, could you share a block diagram to have a better understanding of your end user application where 100 devices information need to be stored

In short, if you store data in flash memory, as long as you have space you will be able to store device specific bonding information

2. In case i have set APP_BOND_DB_MAX_BONDED_PEERS as 5, and all the 5 slots are taken, then if the new connection comes, will it remove the first paired device or last paired device? I mean will it follow FIFO or LIFO pattern?

First data will be overwritten this is usually how the algorithm are designed to efficiently utilize memory. However again this is application specific and you can use the user space to write your own algorithm to change or modify the end user application behavior

3. What is the maximum number of devices you have tested pairing bonding? [‎6/‎5/‎2019 3:14 PM]

In a piconet a testing is done for CFG_MAX_CONNECTIONS number for DA14583 from da1458x_config_basic.h file
