Hello,
I am an engineering student currently working on optimizing the throughput of a firmware using BlueNRG-M2 with a Bluenrg-2 chip in Bluetooth 5.2 (https://www.st.com/en/wireless-connectivity/bluenrg-m2.html#st_description_sec-nav-tab).
My question is as follows:
Can we modify the value of ATT_MTU (Attribute Protocol Maximum Transmission Unit) for this chip? My previous chip was a Bluenrg-M0 in Bluetooth 4.2, and it couldn't have its ATT_MTU value set higher than 23, even though it was Bluetooth 4.2. It seems that some chips, like the MS series, couldn't change the ATT_MTU.
So, I decided to switch to Bluetooth 5.2 with the Bluenrg-M2 chip, which has Bluenrg-2, but I'm wondering if it's possible to increase the ATT_MTU value for this chip and, if so, by how much?
If it is possible, how can I do it once I receive the chip?
I don't find these information in the datasheet I am sorry :(.
NB: I saw that DLE is possible with this ship but i am not sure it is the same as modifying the ATT_MTU.
Best regards,
