nus data rate reduced very much in sdk14.0 compared to sdk12.3

[monster_geek]

Hi,

I am trying to send data from a peripheral with sampling rate of 125 through ble by using nus service. i was able to send all the data (ie. 125 * 4 bytes ) without any data loss in sdk12.3 s132. but when i moved to sdk 14.0, i am losing too much of data, ie only 30-40 packets are received in the ble client. i am using nrf52832 soc. how can i achieve that higher data rate with sdk14.0?

Hi,

Are you getting any error-codes when sending data with ble_nus_string_send()? Could you try to increase the hvn_tx_queue_size?

See this and this post for more information.

thanks siigurd(sorry for the late reply :|) it did help me, and also the NRF_SDH_BLE_GAP_EVENT_LENGTH was 3.
