NUS Nordic UART Service+nRF Toolbox max TX length is 62 bytes

[persimmon]

I run the ./nrf/samples/bluetooth/peripheral_uart example on 52840DK and connect to it using the nRF Toolbox UART section. 

The connection works and I can send messages to the 52840DK from iOS through the log tab.

The problem is that if the length of the message is more that 62 bytes I receive and error in the log saying:

Writing value to characteristic has failed

Error: The reuquest is not supported.

I checked the peripheral_uart, and the 52840DK doesn't receive any message. I am assuming this error is generated by the iOS App. Surprisingly,  mtu  = bluetoothPeripheral?.maximumWriteValueLength on the iOS App is actually 512 bits, but still iOS doesn't send a message longer than bytes.

Hi persimmon, 

I've just sent for review the new version (5.0.4). It takes few days before it's approved on AppStore.
