Hi Musti,
I receive a response from EByte

We don’t have a chart to categorize it, because it is a relative value compared with the value when the module have good signal.

I think you can use that value only for reference, because a less RSSI can be avoid with a lower air rate and so on.

Hi musti,
It’s an interesting question, but I don’t have an answer, so I am writing to Ebyte. I will alert you when receiving the response.

Hi George,
I try to replicate the problem with an example sketch but for me work all correctly.

I use an Arduino Nano 33 IoT and an STM32F103 without RSSI enabled and It seems all ok and I try with RSSI enabled and the same sketch with RSSI enabled and all It’s ok.

Can you help me to find the problem?

I forgot to say that it’s only a visualization issue, the Library work correctly.

Hi Gulpman,
no, you don’t miss anything :P, there is a bug, I’m going to fix it as soon as possible.

Hi Gulpman,
Yes, you must add the correct frequencies define like described here.

Hi George,
Sorry for the late response; I’m not at home these days.

E220 has internal encryption managed by two keys, CRIPT_H CRIPT_L; these keys are used for the description. You can change them with configuration.

	configuration.ADDL = 0x03;  // First part of address
	configuration.ADDH = 0x00; // Second part

	configuration.CHAN = 23; // Communication channel

	configuration.SPED.uartBaudRate = UART_BPS_9600; // Serial baud rate
	configuration.SPED.airDataRate = AIR_DATA_RATE_010_24; // Air baud rate
	configuration.SPED.uartParity = MODE_00_8N1; // Parity bit

	configuration.OPTION.subPacketSetting = SPS_200_00; // Packet size
	configuration.OPTION.RSSIAmbientNoise = RSSI_AMBIENT_NOISE_DISABLED; // Need to send special command
	configuration.OPTION.transmissionPower = POWER_22; // Device power

	configuration.TRANSMISSION_MODE.enableRSSI = RSSI_DISABLED; // Enable RSSI info
	configuration.TRANSMISSION_MODE.fixedTransmission = FT_TRANSPARENT_TRANSMISSION; // Enable repeater mode
	configuration.TRANSMISSION_MODE.enableLBT = LBT_DISABLED; // Check interference
	configuration.TRANSMISSION_MODE.WORPeriod = WOR_2000_011; // WOR timing

	configuration.CRYPT.CRYPT_H = 0x00;
	configuration.CRYPT.CRYPT_L = 0x01;

The default values are all 0.

I will try to publish the E220 configuration article next few days with some additional information.

Hi Leo,
I try to ask here https://new.abb.com/contact-centers

but only some time give me response.

I think a good solution is the Facebook page.

Hi George,
the log says that there is a wiring problem.

17:32:18.057 > ----------------------------------------
17:32:18.101 > The M0 and M1 pins is not set, this mean that you are connect directly the pins as you need!
17:32:18.199 > AUX HIGH!
17:32:18.209 > Complete!
17:32:18.221 > No response from device! (Check wiring)
17:32:18.265 > 12
17:32:18.268 > ----------------------------------------

Pay attention to M0 and M1 settings also.

Hi George,
this week I can’t explore these problems.
But I check all when return.

For the RSSI remember to activate It in the device configuration.

Try to use a structure to check if the problem persists.

Hi Gulpman,
It’s true, and I’m going to adjust something. I reused some schema from the previous article, and I don’t give attention to the single label, only to the connection schema.

But AUX isn’t connected (to the microcontroller) but It’s pulled up.

Thanks for the alert about that issues, if you find something else alert me.

Hi LeoLage,
I check in the protocol manual, and I can’t find that option

Download!

I think isn’t possible to retrieve via rs485.
Try to check in the document.

Hi Tengku,
what configuration do you use on the server and receiver?

Hi Klaas,
sorry but I add a cycling link and I freeze de forum.

Other people have tried to use that device with different results.

E22 Wiring and Constructor Validation

E90-DTU (400SL22P)

But if you configure correctly the device you can use this library.

Good! If you need more help, write without problems.
And if you want, share your projects.
