How can I change the TX_BUFFERS on both nrf51 and nrf52?

[bluetoothbiao]

HI, I get the information frome the sd_ble_tx_buffer_count_get that ,the nrf51 with S110 SD8.0 has 7 count(7*32BYTES) of TX_buffers (I can use 6cnt one time) . The nrf52 with SDK 0.9.2 SDs132_nrf52_2.0.0-4.alpha_softdevice has 3 TX_buffers(2 count can i used).

I want to know that

1. How can I change the tx_buffers size ,or how can I keep the txbuffers always have some data in there?    I have tested the BLE_EVT_TX_COMPLETE event to send data as fast as I can ,that is not fast enough.

Please edit your question and remove question 2-5 and add them as separate questions, or this will quickly get very messy. In regards to question 1. What kind of throughput are you seeing? What throughput do you require?
