Expand description

TWI error.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TxBufferTooLong

TX buffer was too long.

RxBufferTooLong

RX buffer was too long.

Transmit

Data transmit failed.

Receive

Data reception failed.

BufferNotInRAM

The buffer is not in data RAM. It’s most likely in flash, and nRF’s DMA cannot access flash.

AddressNack

Didn’t receive an ACK bit after the address byte. Address might be wrong, or the i2c device chip might not be connected properly.

DataNack

Didn’t receive an ACK bit after a data byte.

Overrun

Overrun error.

Timeout

Timeout error.
