we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...

hi,
I have developed light lightness model with the help of generic on/off and generic level model from the mesh SDK. And I have used these models by making changes in the...
Good afternoon,
I am trying to run the example "direct_test_mode" on a custom board based on a nrf52832.
I have succesfully run the example in two development kits ...
Hi,
I´m using nrf52840 with softdevice S132 and I wonder whether the ble_gattc_conn_cfg_t::write_cmd_tx_queue_size is a queue common for all connections or if it a queue...
I am currently testing DFU updates with nRF52. I have run into a situation where the upload of new image is interrupted for some reason. When I try to run the update again...
