BLE5 & BLE4 Toghter

[yuval]

Hi !

I want to connect 2 of my units to each other via BLE5 long range coded phy (125Kb).

I also want to be able to connect an android / ios phones to each unit simultaneity.

F.E,

1)  My phone will be connected to unit "A". the user will send a command to unit "A" via an my application. Unit "A" will pass the command to unit "B" (which is long away throw BLE5 125k     

     coded phy).

     the results from unit "B" will be sent back to unit "A" and then will be sent back to the phone.

2) i want to do DFU to the units, so i need a way to be able to connect (or send a command throw the air) to unit ("A" or "B") (remember they are on BLE5 125K) and be able to set the units into   DFU mode.

Is it possible? (I intend to use the NRF52840 for this task)

B.r,

Yuval.

Hi,

1) Yes, that is possible. Take a look at the relay example: https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.0/ble_sdk_app_rscs_relay.html

2) Currently we don't have an official DFU Master code running on embedded chip (for example updating an nRF52 from another nRF52 via BLE or UART/SPI). What we officially provide is source code for updating nRF52 from a PC or Mobile phone. But we have some example code of very simple SPI/UART DFU masters running on a nRF52 to update another nRF52. See this link.

Hi,

It is not what i ment !

I ment that "UNIT A" will be connected to 2 devices simultaneously ( 1) Android phone (in 1M speed), 2) to another unit in long range (125K coded PHY) ! Is it possible and how ?!

Also , 1) It is possible the UNIT A will be a "multi peripheral" with 2 different speeds?

          2) Is it possible to UNIT A to be a "peripheral" in 125K coded phy and at the same time "central"  in 1M ?

Yes, It's possible, just do a PHY update request to on the link you want to use coded PHY on.
