soco TC 06 BMS cheater made with arduino

The soco TC does required some info from battery pack, if you want to make your own power pack with own BMS, then it is necessary to have this module. Other wise the bike with show a 94 alarm. This kind of product is selling about 100yan in china.


I have done some test in some previous posts, the communication system of my soco TC is a RS485 with 9600bps.

base on some captured message, when system on but not riding the bike, 



I'm not sure where is the query command comes from, but the one to battery is:

C5 5C 5A AA 01 97 96 0D


Here is a result with arduino 328p

https://github.com/Ldsrc2008/SocoTC-BMS-cheater


I disconnect the battery BMS RS485 port, and connect the RS485 cheater.

No error code is presented(normally you get a alarm94 if TC does not find it's BMS.)here is a alarm code list from soco.


But, my display has no battery indication.

original one
arduino cheater

My guess is that the display unit sent it's own request for data.

Redo my research on net:
this forum mentioned about a decode program

and the repo is here: https://github.com/Xmanu12/SuSoDevs

they do a translater to BT, and use app on phone to decode.

In the github discussion https://github.com/Xmanu12/SuSoDevs/issues/2

with the above discussion, a newer collection of rs485 is here:

https://github.com/stprograms/SuperSoco485Monitor

this part has more info than I found, it gives more items in the response

 BMS Status (Read Response 0xAA5A) 

but I noticed that on bike gouge does not read BMS temp and voltage, it takes only percentage.

seems we can get current /speed(base on rotor speed?) and ecu temp from this.

Heltec ESP32+OLED+Lora, hardware testing

you can easily find some good boards from china, but most of them lack of accurate document... Hrere is an example; https://hackaday.io/project/26991-esp32-board-wifi-lora-32 the board looks good with lora and a 128x64 OLED, but the IIC and reset connection is important, since pin can be muxing easily, so every board could be different. pinMode(16,OUTPUT);  digitalWrite(16, LOW); // set GPIO16 low to reset OLED  delay(50);  digitalWrite(16, HIGH); // while OLED is running, must set GPIO16 to high  and, if needed, edit your Wire.begin() to Wire.begin(4,15); (4 = SDA 15 SCL)  i tested it with the Adafruit SSD1306 and the Acrobotics SSD1306 Librarys  both work.  Display size is 128x64 There are discussions on these boards on TＴＮ as a LORA node..or maybee single ch gateway? Heltec has a git :  https://github.com/Heltec-Aaron-Lee And there is another copy call TTGO https://de.aliexpress.com/item/TTGO-LORA32-868-915-Mhz-SX1276-ESP32-Oled-display-Bluetooth-WIFI

micro SD card for ESP32, on lolin32 with OLED and heltec 32 lora oled

圖片
I have purchased 2 micro SD card holder for my esp project. First I would like to test with heltec esp32 lora oled module. this module uses: sck=05 MISO=19 MOSI=27 SS(lora)=18, then I assigned 21 for sd SS and there is a lib in esp32-arduino, which use SS default at 5 I took the example and use SD.begin(21), but I alway get the error: entry 0x40078a9c Card Mount Failed But I do saw once that it read out the sd card type and volume. Not sure it's the issue of lora sd card swithing, or it just can't work. The other esp32 card I have is an wemos esp32 oled, it did not leave me too much pins, I need to find out how to connect sd to it. But I have wemos D1 mini esp8266 on hand, and connect it as:  * The WeMos Micro SD Shield uses:  * D5, D6, D7, D8, 3V3 and G  *  * The shield uses SPI bus pins:  * D5 = CLK  * D6 = MISO  * D7 = MOSI  * D8 = CS It's not working with the example in the arduino IDE 1.8.5, which marked SD(esp8266), but it w

AIS0. understanding AIS NMEA 0183: How it's coded

For my boat tracking system, I found out that using AIS format seems to be a good idea, at least I don't have to worry about how to present boat data, since there are already plenty things for do this on mobile phone or PC. Here is what I read: http://catb.org/gpsd/AIVDM.html Looking into AIS NMEA0183, it has much more application then I think. Such as MOB device, epir, aid to navigation device...etc, all are included. it use the first few char to indicate the function: Table 1. AIS talker IDs !AB NMEA 4.0 Base AIS station !AD MMEA 4.0 Dependent AIS Base Station !AI Mobile AIS station !AN NMEA 4.0 Aid to Navigation AIS station !AR NMEA 4.0 AIS Receiving Station !AS NMEA 4.0 Limited Base Station !AT NMEA 4.0 AIS Transmitting Station !AX NMEA 4.0 Repeater AIS station !BS Base AIS station (deprecated in NMEA 4.0) !SA NMEA 4.0 Physical Shore AIS Station It can also be used between device on boat for message communication, AIVDO The
