This is not question of DA14531, I hope to search for help to post here.
Maybe someone has faced this question before, maybe they have found the solution.
I made 10 clients configured with BLE module,and the server developed with Delphi.
My hardware configure:
1) Windows 10 on surface Model 1769;
2) Marvell AVASTAR Bluetooth Radio Adapter / Microsoft Bluetooth LE Enumerator in surface;
3) ARM Cortex M0+ + DA14531 module.
In server side, I use TBluetoothLE to connect with DA14531.
It can find all 10 clients, but can only connect with 8 of them, other 2 clients can't be connected,
The error raised: Access not allowed or no service available.
I don't know which layer limit it:
-Marvell AVASTAR Bluetooth Radio Adapter
-Microsoft Bluetooth LE Enumerator
-Delphi.TBluetoothLE
There is no property / method to change connection count for TBluetoothLE.
And I did not find info on changing connection count for Win10.
Any suggestion?
