Arduino nano 33 BLE Sense UART is not working properly about arduinocore-nrf528x-mbedos HOT 7 CLOSED

@gianmarcov the problem is not the non implementation (because it gets inherited by Print.write() so it executes the slow byte-by-byte write) but the return value of putc() .
A patch is coming 😉

Hello,

I think i found the Problem:

I call in my library Serial.write(buf, len) and i saw it's not implemented, so now if i write every single byte via for loop it works.

please implement Serial.write(buf, len) or write in the documentation that is not implemented yet, i spend 2 days and a lot of time searching the cause in my lib.

@gianmarcov can you give a spin to #21 and report if it work for you? Thanks!

@facchinm when i'm home, i will test the changes and report back. grazie mille!

@facchinm bad news, replaced in the Version 1.1.2 the Serial.ccp and Serial.h with yours, but it doesn´t works.

@gianmarcov sorry to hear that. Do you have access to an oscilloscope to check what is going on? From my tests all bytes are being sent (after the patch) and calling write() is blocking as per Arduino API specifications, so it should work just as every other core

@facchinm yesterday i attached my Rigol Oszilloskope and decoded de TX Pin, i have the same result using for-loop write and write(buffer, len). So the patch is working right, the bytes are identical.
The Issue is resolved ;-)
