I have an nRF52 paired to a central device. In order to delete the pairing on the nRF52 I clear the persistent data (dm_init_param_t).
I notice, however, that even though...
Hi all,
I'm a grad student trying to innovate on the BLE concept. I require a continuous signal as a source: preferably unmodulated, but a long duty cycle could also work...
The NRF52 product specification (aka, datasheet) has 3 chapters in it all relating to TWI: TWI (chapter 49), TWIM (chapter 33), and TWIS (chapter 34).
Which section (TWI...
Hi,
I'm trying to interface SIM808 with nrf51822 over uart using nrf_drv_uart. Everything works well for some time, but then uart starts reporting error code 1, NRF_UART_ERROR_PARITY_MASK...
