Thanks Gordon for reply. I thought that I did something wrong because I could not find my esp32 with NRF Connect. But the thing was that I looked for MAC that I got from
NRF.getAddress()
->"de:ad:de:ad:de:ad"
. In fact esp32 advertising with MAC fromgetSerial()
->"30aea488-a16c"
->30:ae:a4:88:a1:6c
.
I just trying esp32, that is not mine by the way :), as starting point. So if I'll start some serious project I'll definitely buy one of your official boards to have more reliable BLE support and help the Espruino Project. But I can't afford it now. -

Hi everyone! Can anyone tell what I'm doing wrong?
Code below returns:
>FIXME WARNING: check error not implemented yet:0
and sometimes:
WARNING: update connetion params status = 0, min_int = 0, max_int = 0,conn_int = 6,latency = 0, timeout = 500
setInterval(function() { NRF.setAdvertising({ 0x1809 : [95] }); }, 3000);

Sorry, I can't post that code. I have deleted it. I believe that I didn't use
.end()
. So it can be the reason.
Though there is a part of new code that works fine now:// On POST Request Handler function onPOST(req, res) { let data = ''; req.on('data', d => data += d); req.on('end', () => { try { let obj = JSON.parse(data); mod = obj.mode; res.writeHead(200, { 'Content-Type': 'text/plain' }); res.end('Mode Set'); } catch (err) { res.writeHead(200, { 'Content-Type': 'text/plain' }); res.end(`Error: ${err}`); } }); }

Can you post your code?I've found what is the source of problem. If you don't put
callback
function (as in example below) into POST handler your memory usage increases with every POST request and program after a while crashed. With suchcallback
everything works now, I think :)// This handles any received data from the POST request function handlePOST(req, callback) { var data = ""; req.on('data', function(d) { data += d; }); req.on('end', function() { // All data received from the client, so handle the url encoded data we got // If we used 'close' then the HTTP request would have been closed and we // would be unable to send the result page. postData = {}; data.split("&").forEach(function(el) { var els = el.split("="); postData[els[0]] = decodeURIComponent(els[1]); }); // finally our data is in postData console.log(postData); // do stuff with it! console.log("We got sent the text ", postData.mytext); digitalWrite(LED1, postData.led1); digitalWrite(LED2, postData.led2); // call our callback (to send the HTML result) callback(); }); }

Using string UUID (16bit or 128bit representation) throws an error
ERROR: empty UUID type
. Integers between 0 and 0xFFFF works fine.NRF.setServices() docs note:
UUIDs can be integers between 0 and 0xFFFF, strings of the form "ABCD", or strings of the form "ABCDABCD-ABCD-ABCD-ABCD-ABCDABCDABCD"
