BLE Click boards usable as controller (caster)?

[ravu al hemio]

Hello everyone,

I was looking at all the available Bluetooth Low Energy (BLE) Click boards and it appears that some of them (e.g. the BLE 12 Click) use chips whose command set implies that they can only act as a BLE peripheral (slave) but not as a BLE controller (master).

For example, the BM832A (on the BLE 12 Click board) has commands to advertise itself (AT+ADSTART=...) and an event that a connection has been established (+CONNECTED) but no command to connect to a device. This would imply that the BM832A can act as a peripheral, advertising itself to possible controllers and letting them connect to it, but not as a controller, scanning for other devices and connecting to them.

Is there an overview available somewhere which BLE Click boards can act as BLE controllers and which only as peripherals?

Thanks in advance!

Hi Ravu,

Unfortunately, we don't have an overview of which BLE Click boards can act as BLE controllers and which ones only as peripherals.
We use them all as peripherals, so you have to check the datasheet if you need to use some of the BLE click boards as master.


Kind regards,
Tanja

as @Tanja_Kovacevic said, you need to take a look at the datasheet for the BM832A module - It's linked from the BLE 12 Click board product page.

Page 8 tells you that this particular module uses a Nordic nRF52810 chip: this is a "base level" chip - I don't think it is recommended for "controller" applications.

You would need to check with Nordic:
