💬 Easy-Peasy Amplified MySensors Serial Gateway

[NeverDie]

I had a chance to test the module more thoroughly, and it appears to work just fine at 2mbps also. So, as of this moment, everything seems good, and I'm not aware of any problems. :)

is there a connection diagram?

The newer E01-2G4M27D has more powerful transmit and more sensitive receive capability:

I know this thread is old but it seems the most relevant. I just tried to compile the standard GatewaySerial.ino sketch using Wemos D1 mini as board type and I get error:

MyMainESP8266.cpp:95:9: error: 'cont_can_yield' was not declared in this scope;

I'm using MySensors Library v2.3.2

I'm assuming this used to work. Is it broken or I am doing something wrong?

Great to see you again @KevinT

It is broken, and you are doing something wrong :-)

Use the latest supported version of the board definitions. See https://forum.mysensors.org/post/114086

Hi @mfalkvidd
I rolled back the esp8266 library to 2.6.2 and it compiles.
Is there an upcoming release to fix this?
Thanks :-)

@KevinT did you read the thread I linked?

[KevinT]

Yes, Lol, you have 2 PRs but both have issues. I looked, but I didn't manage to find them on Github/MySensors. I did read that espressif updated their esp8266 core to use standard Arduino yield functions. I guess it's related to that.

[mfalkvidd]

@KevinT should be one of these https://github.com/mysensors/MySensors/pulls?q=is%3Apr+esp8266+sort%3Aupdated-desc+

That issue is caused by the newer ESP8266 core changing yield functions. Downgrading the ESP8266 core to v2.6.2 (or v2.7.4 depending on your board setup) remains the most reliable workaround until those MySensors core PRs get merged into a main release. Keep an eye on those GitHub PRs for updates on full compatibility with current core releases!
