HM-10 BLE node SoftSerial issues

EmielA last edited by

Hello,
I build a Mysensor 1.4 version node with a Arduino Nano and the NRF24. And made this connect with a HM-10 BLE module (bluetooth low energy module), and connected it on pin 4 Rx and 5 Tx and controlled it by asynch rs232 serial AT commands. on a SoftSerial bases. The goal of my project is to detect BLE beacons. measure their distances to the sensor and sent the distance and the MAC adress of the beacon to the gateway.
When I tried to compile I got interrupt vector errors. After searching the web I found that I had to adjust the PinChangeInt.h and uncomment the #define NO_PORTB_PINCHANGES and also for port c and d. Then the compile went well.
But I noticed then strange behaviour. When I sent AT commands and wait for a response on the SoftSerial port it misses sometimes characters. Its not reliable anymore. The scanning and detection stops after several minutes.
How can I use SoftSerial and the 1.4 Mysensors together reliable?

@eiten said in Saving last known good state, but not in EEPROM: utility meter in home assistant This is exactly what I am seeking! Thank you! PS I truly enjoy reverse translating! It teaches me how to better understand my first language and it gives me alternate words to use in searches. So a second thank you! "Regelmässiges Zurücksetzen" would be best translated to English in this context as "Periodic Reset". In the English version of Home Assistant it is called "Meter reset cycle" (I remember seeing "keep dry" translated as "do not take in shower with you"

@tekka Is there any changelog to it also or it was just made officially available again? although last online status was 22 AUG 2020, so anyone else can confirm anything about it? I'd just be cautious without confirmation.

Just for completeness: the right way to do this is to add the json under ~/.platformio/boards and the other files as described in https://community.platformio.org/t/how-use-a-same-chip-but-with-different-environment/18082/4

@OldSurferDude well, the ESP8266 is limited to 4 TCP clients in arduino IDE. This can't be really increased. I did som experiments and you can set it up to 15, but after the 5th client on my web server, I got a freeze. Maybe you got something wrong. #define MY_GATEWAY_MAX_CLIENTS 2 defines how many controllers (eg Home Assistant) can connect to the gateway, not how many sensors/MySensors devices. And yes, you can have multiple TCP gateways in HomeAssistant. I got an NRF24, an RFM95 long range and a RFM95 short range gateway (all based on ESP32) on the same Home Assistant. Regards, Edi

Thanks, I'll keep this in mind if I decide to debug it. I realized that I am also tired of patching the gateway through to the doctor container inside an LXC so now I am looking at creating an esp gateway. Just need to check if I can find a pcb on here. Thanks again!
