Strange output on UART1 : chg_B

[sharkx]

SDK version is 1.3.0

I have two apparently identical modules; software-wise they run the same code; hardware-wise, they're identical as far as I can tell.

However, one of them is printing this to the UART1, besides my own info and other system output.

Code: Select all

chg_B:0
chg_B:-60
chg_B:-120
chg_B:-180
chg_B:-240
chg_B:-300
chg_B:-360
chg_B:-420
chg_B:-480
chg_B:-540
chg_B:-600

Then it restarts at 0, -60, -120, ... Each line comes out about every second. It's pretty annoying and it makes other output hard to follow.

What's strange is that ONLY ONE module is doing this; his twin module doesn't.

Anyone has any idea what can be the cause ?

Hi,

Which SDK are you using, ESP8266_NONOS_SDK_V1.3.0 or ESP8266_RTOS_SDK_V1.3.0 ?

If it is ESP8266_NONOS_SDK_V1.3.0, please have a try with the latest ESP8266_NONOS_SDK_V1.5.1.

Thanks for your interest in ESP8266 !

Thanks for the reply.
It is the NON OS 1.3.0. It was the latest version I could fit into the 172 Kb.
Now that I know how to increase that, I'll try the latest version.

Well... the 1.5.1 gets me dangerously close to the 236 Kb limit for the firmware.
So I guess I win't be able to use it.

Strangely enough, once I reverted to the 1.3.0 SDK, the messages disappeared...
