Hello. We are evaluating the nRF9151 SiP as a potential solution due to its low power consumption and compact form factor. However, our team has limited experience with firmware development for this platform, so we first need to assess whether our use case is technically viable.
Our goal is to record (or stream) a short audio clip (15–20 seconds) and transmit it to a cloud server. We're aware the nRF9151 includes an I²S interface and an LTE-M modem so, in theory, it should be possible. While we understand that larger audio files could pose challenges over LTE-M, we believe our relatively small audio size may make this feasible. Our case of use requires instant audio transmission so we cannot store the audio and send it later via Wi-Fi, we also can't send it via BLE. Our device should be completely independent and have a really small form factor, that's why we think nRF9151 should be perfect for this.
We want to confirm with more experienced engineers on whether this approach is practical and possible before moving forward with development. Also, it would be really helpful having a good foresight of software resources required for our project, like libraries available in the nRF Connect ecosystem that can aid us on our project planning, something like LTE audio streaming for this platform. Any additional information we can have, that can help us orient the work to be made, we would be really grateful to receive.
Thank you in advance to this community.
