nrf52832 BLE MESH

[Sunil vignesh]

HI, I am using nrf52832 soc and i develop our own module. i need to create a mesh network within the device.

I am using segger embedded studio 3.34 (windows 10)  and SDK 15.2 

I want to run a light switch demo in mesh network

when i build the example light switch client i got the error

boards.h: No such file or directory
ble.h: No such file or directory
app_timer.h: No such file or directory
nrf.h: No such file or directory

i don't know where to interface this hex.files and also how to interface the nrf15.2 to this nrf52 mesh

Hi.

You have to include the header files boards.h, ble.h, app_timer.h, and nrf.h in the preprocessor definition, as explained here.

 

i don't know where to interface this hex.files and also how to interface the nrf15.2 to this nrf52 mesh

 I'm a bit unsure what you mean by this.

Best regards,

Andreas

Hi Andreas

Thanks for the reply..

I got those error out by   adding the prefect global macros

but

now i got an new  error

1. i don't know how to interlink these codes

 What do you mean by "interlink these codes"?

2. If  i connect the ble_uart code with UART app within few seconds its disconnecting ...

 Have you tried to debug to see why you disconnect?

Best regards,

Think is after download the ble_uart code to nrf52832 DK.

in another board  I download the Light switch server code.

in nRF MESH app

only shows light switch server device. not showing ble uart device.

while i search the device in nrf uart app.

nordic uart device as shown and the after connecting the device within few seconds it will disconnected . while debugging the code it just show disconnected only.

Hi.

Could you try to connect using nRF Connect?

Note that UART over Mesh is not implimented, the ble_app_uart_coexist example uses BLE for UART, and Mesh for light switching.

HI,

I need to create the communication between client and servers

perfect MESH_UART code is there ?

[AndreasF]

Hi.

What sort of communication do you want?

HI,

I need to work on the HOME IOT application. for that i need one client and multiple servers (upto 15 - 20).

In that client will query the each server regarding status and sensor output. (note : each Server has different sensor values).  with respect to server data. client has to take necessary actions.

And client has to connect with mobile phone show that it will show the All Server data via one client .

For this I need to work in BLE_UART peripheral  and i need to work this in MESH network to achieve long distance

Please Give me a solution ..! 

Thank you.,

Sunil

Hi.

How long range do you require between the peripherals? How long range is there between the edges of the network?

If the range is not long, then you could create a star network with one central and up to 20 peripherals.

If the range is very long then I suggest a Mesh network.

But as I have said in my previous reply, BLE UART is not a Mesh solution, it is BLE.

Best regards,

Andreas

Maximum distance between the each peripherals will be 75m- 150m.

and edges of the network will be around 600 - 800m

as of now i got maximum distance of  25m between two devices (not in line of site).

with internal PCB Antenna (length 25mm)

the application we are going to use :

HOME automation

Fitness tracker

Health care

HI,

I have a doubt

Is BLE_central can able to scan and display the MAC address and name of the peripherals ?  -  is there any code related to that

2. by using BLE_central code . it will scan and display the MAC address of any Bluetooth mobile phones ?

Hi.

For the benefit of the other forum members, can you please create a new ticket and ask these questions there? So that other forum members can find it. You will get the answer to these questions there. I will close this ticket, I hope this is ok.
