[quote user=""]What kind of network would be optimal to implement in this use case where we have one central unit and a few peripheral units ? Communication is unidirectional - from peripheral unit to the central unit.[/quote]

Standard star-topology. You do not need a mesh unless you intend to connect >19 central's together or you need the extended range a mesh provides. Meshed networks also require a lot more energy.

[quote user=""]Should we implement a BLE mesh or to exchange the message in BLE advertisement mode or something else?[/quote]

Use BLE advertisements.

You can order it directly from the link on crowdsupply for evaluation order. Contact sales at i-syst dot com for volume production.

Documentation download here https://sourceforge.net/projects/blyst-nano/files/docs/.

It is 100% software development with SDK. You can flash prebuild hex examples from the SDK directly. Beside the SDK there also more open source software support here https://github.com/IOsonata/IOsonata

And blog pages on how to write BLE firmware easily here

Development board with builtin CMSIS-DAP is also available here https://www.tindie.com/products/hnhoan/bluetooth5mesh-nrf52832-arm-m4f-nano-devkit/

MicroPython port is also available on main MicroPython github

The IMM-NRF52840 module will be available around jan time frame.

Thanks for the suggestion, Nguyen Hoan Hoang. Where can I buy the module, download datasheet and see some more characteristics?

Can I develop the firmware by using Nordic's SDK?

Sincerely,

Bojan.

This module is based on the nRF52832. It is extremely small 7 x 10 x 1.6mm certified. https://www.crowdsupply.com/i-syst/blyst-nano. Everything is builtin 32KHz crystal and DC/DC coils for low power. No extra components needed on your PCB. A nRF52840 based module 9 x 14 x1.6mm is being certified.

This module is being used in this beacon product https://iqonboard.com
