Hi.

Sorry about the delay.

Yes, that is most likely the cause.

I would say that a performance drop is to be expected.
A with a drop in throughput, packet loss and range issues is likely to occur.
With the ble_app_uart_coexist example the node has to toggle between ADV bearer, advertising and keeping the BLE connection going.

Some measures might be able to improve this, like increasing the BLE advertising interval, to allow more time for the Mesh stack.

Best regards.
Joakim

Hi Joakim Jakobsen,

Thanks for the reply and that was a great start.

I tried working with ble_app_uart_coexist and it was working as expected. But something caught my attention.

Test setup:-
nRF52840DK - light_switch (provisioner)
nRF52DK - light_switch (server)
nRF52DK - ble_app_uart_coexist (client)
android phone - nRF UART

so, here, without the android phone, things are working relatively ok, but once we have connected the android phone, mesh client reception efficiency got reduced significantly. Say out of 10 packets sent from server(button 0 pressed), only 7-8 got registered in client.

Has this got something to do with radio allocation between BLE and mesh?

Since my final requirement is to implement HID device within a mesh network, packet loss and latency should be kept bare minimum.

Thanks,

Hari

Hi Hari.

I suggest you take a look at this blog post about our nRF Mesh smartphone app.

Also, take a look at this thread and the answers from Hung.
