Now i have successfully read 3 ADC channels with time period of 244 microSecond on terminal. But i have facing problem this accelerometer data is send to my mobile apps but it is noten-USTelligent Community 13Thu, 31 Aug 2017 09:17:50 GMThttps://devzone.nordicsemi.com/thread/97002?ContentTypeID=1Thu, 31 Aug 2017 09:17:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bb16ded9-37f8-47b0-8124-ff29e05705f3run_ar<p>1 and 2. Make sure there are tx buffers available. For maximum throughput you should call sd_ble_gatts_hvx until you get NRF_ERROR_RESOURCES (BLE_ERROR_NO_TX_PACKETS for older SD versions). When that happens, wait for BLE_GATTS_EVT_HVN_TX_COMPLETE before you call sd_ble_gatts_hvx again.</p> <ol start="3"> <li>Yes, you can use a longer att MTU, both with or without data length extension.
