Re: LoRaWAN ESP32 IDF component

Ok. No problem and looks like a very viable solution if you are ultimately interested in just getting the project done and porting LMIC is only an enabler. Microchip RN2903 LoRaWAN module looks like a nice candidate indeed.

Re: LoRaWAN ESP32 IDF component

Nice and sounds promising! Share your component early on Github so we can all contribute. I'm busy for the next couple of weeks, but I can always take a look (and shift priorities...)

Re: LoRaWAN ESP32 IDF component

No I did not and I'm still keeping an eye out. The Lua RTOS ESP32 project has a component which is highly coupled with all Lua magic from the project and is not a good candidate to be ported. Porting the LMIC myself is something is were I burned and lost some time, but as also mentioned elsewhere, t...

LoRaWAN ESP32 IDF component

Hi there,

I'm looking for a LoRaWAN IDF component I could use to drive the LoPy SX1272 chip (or similar using SPI). The Lua RTOS project has something interesting, but I was wondering if any of you guys have been using this already or if there's something else around

Thanks,
Martijn

Correct way to pass struct as an xTaskCreate parameter?

Hi all, Perhaps a bit off-topic and perhaps a beginners error, but this one is biting me with all erratic behaviour on the ESP32. So please lend me your ears. Within an app.h I hold the definitions for structs I use for different tasks. In this example I have a PixelTask which drives a Neopixel depe...

Re: Certification Western Europe ESP-WROOM-32

Thanks for the replies, No we are not an electronics engineering company. We create software for the last 20 or so years, mostly sensor or metering related with /a lot/ of data. This was mainly co-location, but all this moved to AWS the last 7 years - starting with EC2, moved on, and we've never loo...

Certification Western Europe ESP-WROOM-32

Hi all, So we are designing some boards which will be used in B2B projects only in small quantities (<100) and the projects will have a beta state for some considerable time. But still, could easily be this device some day wil take off and that we will be using it in a consumer environment as a spin...

MQTT_TX_BUFFER_TOO_SHORT_ERROR on AWS IoT embedded C

Hi there, We've been busy using the AWS IoT from the embedded C within the IDF. We also use shadow and everything works nicely, be it that initializing/retrieving the shadow state can sometimes cause random crashes which we have still under investigation. We run a publishing loop just like the examp...
