Evaluate the maximum working connection to a BLE central (Dongle or cellphone)

TTN

Hi,

Currently, we have a device that uses the nrf52832 custom board as a Peripheral notify to send the data collected to Pixal 5 (central),

We have a cellphone app to call the data received by the mobile phone to show that at present,

we need to evaluate how many peripherals can be connected to a central and can also operate normally.

I would like to ask how to evaluate and compare Pixal 5 and nrf 52840 dongle as BLE central.

What about the maximum number of connections in operation?

At present, a peripheral will transmit(MTU) 200 bytes of data 10 times per second, 10 sets (2000 bytes) of data will be 2 Kbytes,

    Hi,Do you want to replace the Pixel 5 and use the nRF52840 dongle as central instead?

    No, we want to replace this device's bluetooth module for demo.

    The device have bluetooth module but the module is unstable, so we want to replace the bluetooth module by nrf dongle.

    The device's system is android, so should i use BlueZ and program a host on the nRF52840 dongle?

    There is some  support for BlueZ on Android, but I am not sure how well it works. If you get that working, then you program a Bluetooth controller on the nRF. For instance Bluetooth: HCI UART if you use UART between the Linux host and the nRF Controller.
