Unable to transmit at 100Hz with nRF51822

[Abhishek Satish]

I've created 2 custom PCB boards, 1 main board and 1 dongle based on the nF51822. The Dongle board uses the default ble_app_uart_c code. The main board transmits to the Dongle board every 8ms (it is a ble_nus_string_send() call controlled by the APP_TIMER and called every 8ms) On both the boards, the minimum connection interval has been set to 7.5ms and maximum to 7.5ms as well. However, I can only achieve a maximum transmission frequency of ~60Hz. I should be able to get ~133Hz. Can anyone advise on how I could do this? I just need to get to 100Hz, not even 133Hz.

I strongly recommend checking the actual numbers in connection events (connect / conn param update). Android, for example, uses a 15ms interval which would roughly fit your 60Hz.

Thanks for the reply! I'm actually doing an nRF51822 to nRF51822 connection. But I'll still try checking this out!
