Re: EN300328 RSE ESP-WROOM-32 Failure

Does it look like the testing may be suspicious or maybe a bad board or something? I'll admit that my initial thought was maybe something was done wrong, plus we've been dealing with a test engineer that doesn't seem to be very experienced and the language barrier has been pretty severe as well. Unf...

EN300328 RSE ESP-WROOM-32 Failure

We have a product that is going to market that needed to run through CE RED testing. It uses the pre-certified ESP-WROOM-32, but because we have a second low power radio on our PCB we had to re-run the testing of the module. As part of this testing they had to run the ESP32 in its stand-alone test m...

Re: Clear the BLE whitelist

Did you have any luck?

I'm more curious if you were able to even get whitelisting to work at all? I'm trying to allow connections only from a specific phone and no luck as of yet.

Re: uxTaskGetSystemState() working BUT runtime stats vary wildly

From what I could tell, the xthal_get_ccount() function returns a different value for different cores. So I wrote functions equivalent to yours, but CPU ID aware. extern uint64_t get_run_time_counter_value(void); extern void init_run_time_counter(void); #define portGET_RUN_TIME_COUNTER_VALUE() get_r...

Re: smp_br_connect_callback is called on unexpected transport 2

Did you ever figure this out? I'm getting this message on connect: BT: smp_br_connect_callback is called on unexpected transport 2 and this on every notify event BT: bta_to_btc_uuid UUID len is invalid 0 I'm having lots of issues with BT and wonder if this is somehow related or if these error messag...

Re: ESP32 BLE - iBeacon scan not working reliably

Did you have any luck with this? I'm having some similar issues. If I scan on my Android phone using the "nRF Connect" app, I can see advertisements coming from my device very regularly at ~25ms with nothing more than ~50ms or so. Doing the same scan on ESP32 I get some random gaps of around 400ms o...

Uart Rx/tx

Does anyone know if it would be possible to configure the same pin for both UART TX and UART RX simultaneously? I have seen this feature in certain other micros and it can be used, for example, on a LIN bus or rs485 where there is a single wire/signal bus and extra error checking is not required. I'...
