Hi,
I am just starting with Blynk and am implementing it in an existing project that uses a sim7000 GSM.
This project runs multiple tasks (all on core 1) and I have implemented Blynk to also to run in a task (on core 0) so all can run more or less in “parallel”.
The code is event based (like Blynk gets a notification when another object wants to send a message) but there are some processor time heavy components…
Problems I am having are cmd errors (and thus reconnects).
I am trying to play with the following defines to make sure other tasks also get processor time and blynk is not starved (but to be honest I am not exactly aware if these defines have the result I am looking for):
#define TINY_GSM_YIELD_MS 1
#define BLYNK_RUN_YIELD() { delay(1);}
#define BLYNK_SEND_CHUNK 64
#define BLYNK_SEND_THROTTLE 20
I first initialize blynk, then the task is started which runs the blynk.update and processes messages that need to be sent (which are queued).
Below the code parts I use related to blynk and some logs.
Hope anybody can point me in the right direction and help troubleshoot/tweak this.
thx!
