1.I do not plan to add anything to this project. he as there is. Just an evaluation module.
...Logical continuation of this project:

@magpern I think that perhaps the problem with the i2c bus. The revision of the chip. Try to disconnect the bus before going to bed and then initialize again.
@scalz said in What did you build today (Pictures) ?:
This evening I assembled another dongle (and a few other boards).
@nca78 as you asked, here is a pic during tests. Tiny dual rf dongle board, isn't it
This customization boards adafruit? I've customized the Board Sandeep Mistry.
@scalz How do you plan to use your dongle? Just as coordinator? or only as a gateway mysensors? Have you tried using it as a combo? zigbee quite unceremoniously uses the resources of the mcu.
@jeremushka said in 
Safe relay node:
Have you moved to nrf5 for this concept or finally decided to keep the current design which is working well ?
In the process on nrf52840, but most likely it will be a zigbee(although nothing prevents to make its software under Mysensors that's already available in the Arduino IDE for 52840). The problem with the Mysensors is to support slow and weak chips, the backward compatibility problem does not allow moving forward.
Hi, everybody. Modules nRF5 with RFX2401(signal amplifier) control the amplifier from the legs of the microcontroller, as a rule, r0.20 and P0.24.
Do I understand correctly that gain control is not implemented in mysensors for nRF5 modules with amplifiers???
It probably can be done from the sketch, including a strengthening of the:
digitalWrite(TXEN_PIN, high);
digitalWrite(RXEN_PIN, high);
send.(..
digitalWrite(TXEN_PIN, low);
wait.(..
digitalWrite(RXEN_PIN, low);
But there is also internal communication (which is formed inside, for example - find parent, registration..), the functionality of the repeater, how it should be?
Today I finished printing the case. Turned out to node with sensor bme280 and e-ink display, running on nRF52840 from SKYLAB
In one of the photos still have the sensor with bme280 working on nrf52840 from EBYTE. ...This is the previous project.
