Is it possible to develope a small iot device 30x30 mm with the setup as described here ?
nRF52805 and nRF9160,
needs to send and receive voice from earbuds, and music with 0,5 mbit from Spotify.
and possible the worlds first 5g earbuds ?

And maybe someone wants to join me to make this pcba and get it to mass production ?
Hello,
I'm not sure I understand the IoT device. The nRF52805 does not support BLE audio. Please see our Audio application product page. The nRF9160 does not support voice over LTE and is not designed for music streaming, as this would be too power hungry for the applications the nRF9160 is intended for. Please see our low power cellular IoT product page for more information.
Kind regards,
Øyvind
The nRF91 series is not intended for large data throughput over LTE. It is design to handle low power IoT sensor data. If you look at our whitepaper Best practices for cellular IoT development it states a maximum throughput of 300kb/s of download speed using LTE-M, while NB-IoT (NB2) can reach 127kb/s. The device does not support the same 4G/5G technology as many mobile devices today, only LTE-M and NB-IoT (LPWAN).
The nRF9131 is designed for DECT NR+ applications, but does support cellular as well. Note that the device will need more certification from your side if you want to use this for any type of cellular application.
Tnx, I need to make this work with the Nordic chips. So nrf 9161 supports 300 kbit download or 375 kbit ? I then need to stream directly in lc3 sound (bluetooth codec) from server. Then it can be delivered to the nrf 5340 and earbuds like Aurvana Ace directly without decoding and encoding. The voice commands can also go to the server in lc3 or wav (pcm) of maximum 20 seconds at a time.
Er båndbredde lik på både 9160 og 9161 ? Er det isåfall bedre å bruke 9160 ?
The nRF5340 side and streaming BLE Audio from it to ear buds sounds good. However, the audio streaming from the nRF9160/61 sounds like a bigger challenge. As mentioned, the nRF91-series is not design for this use-case, but you are welcome to try.
Tomas Adri said:9161 supports 300 kbit download or 375 kbit
The Max throughput (DL/UL) (theoretical) refers to 300 kbps download and 375 kbps upload. Note that the speed may vary from network to network with regards to low power wide area (LPWA) technology.
You may try to implement a streaming feature to the nRF9160, however this is not something we have support for and you will need to implement this feature on your own I'm afraid.
Kind regards,
Øyvind
