Dear Nordic company,
I am writting to you in order to get some information about buffer sizes in your aplication. I think, I am bale to modify buffer size and maximum number of devices, that could be connected to nrf9151 or into another your devices. I found some CONFIG variables, but I am not sure if I understand to them correctly.
CONFIG_NET_BUF_RX_COUNT -this variable is for configuration of number of receiver buffer. So if I understand to this correctly, this number is saying how many device could be connected to nrf9151 (via TCP or UDP), or what number of connections with my devices could be created.
CONFIG_NET_BUF_TX_COUNT -the same as with RX. RX and TX count could be the same. In many options. Am I right?
CONFIG_NET_BUF_DATA_SIZE -this parametr tell to us what is size of each buffer. But default value is 128. This is very small value to be in bytes. So is it in packets? When packets could be maximum 2048 bytes length. Did I understand to this correctly? Data size is measured in packets?
CONFIG_NET_BUF_FIXED_DATA_SIZE -this parametr is boolean. If I set this to y value, it says, that my buffer has fixed size, so it can oveflow if I will not be so fast in their reading. But if i set value of this config to n, buffer could allocate memory in dynamic way. So if apper situation, that could my buffer overflow, Zephyr allocate much space for my data (if is it possible). I am I right?
What are parametrs for Serial LTE application, that I could use in Quick start menu in nrf Connect? How many clients I am I able to connect into server? What is buffer size (in packet, if I count with packet maximum size 2048 bytes) for each connections?
Kind regards
