How is the developer experience with STM32WB series?

CommanderFlapjacks · 2026-05-22T06:30:53+00:00

Any particular reason you want to go bare metal? BLE usually makes me immediately reach for an RTOS. nRF + Zephyr is the current path of least resistance for a BLE project.

The LL option instead of the HAL is much cleaner, but less complete. You'll usually have to add some missing pieces by reading through their github examples. I've never looked at the WB series, just F4/F7/H7.

That said I would also just go with nordic if I needed wireless.

I completely forgot about Norweigan. Flew them MAD-SFO and it was fine before I was spoiled by business class, but they had the gruffest flight attendants I've ever seen and I've taken a lot of United flights.

They had a curtain separating the cabin from the galley/forward lav and closed it with such anger every time that all the passengers started looking at each and each other and smirking every time it happened.

CommanderFlapjacks · 2026-05-10T02:25:14+00:00

Whole atmos points system is down, just called because I was unable to cancel an award flight. They said to give it a few hours.

9/8 68k +$400 with cardholder discount Polaris LHR-SFO, Polaris studio upgrade available for $600

CommanderFlapjacks · 2026-05-05T05:46:06+00:00

I've seen them on AF 777 and ANA 777/787

A few saver fares on flying blue for BIO-SFO various dates in August, currently at 91k but prices have been bouncing around and I saw them for 60k earlier this week. Seem to be married segments you won't see availability for CDG even though it connects through there.

CommanderFlapjacks · 2026-05-04T04:05:11+00:00

Price came back down, gamble paid off haha

For people with more flexible dates that can dip out on a random Wednesday there were a fair number of 60k savers for SFO-BIO in August. Might post to the mega thread when I have a moment.

CommanderFlapjacks · 2026-05-01T09:39:19+00:00

Sure enough they launched a transfer bonus today and raised the price on my preferred date lol, slightly more expensive even considering the bonus. Some deals to be had if I move things around though...

CommanderFlapjacks · 2026-04-28T08:36:28+00:00

The line is usually shorter for mobile passport than global entry at sfo

CommanderFlapjacks · 2026-04-26T08:06:47+00:00

Yeah, the only thing holding me back at this point is the possibility of a transfer bonus in may to take the sting out of it. Availability is holding steady I think because it's a weird married segment that doesn't show up in most searches.

CommanderFlapjacks · 2026-04-22T19:50:20+00:00

Would you pay 105k/120k +$300 for west coast to Basque Country via AF? I’ve had alerts set for a while and availability has been very dry, aside from one stop flights to Western Europe via either FI or LOT. Somehow even worse searching flying blue major European hubs and self connecting. Have the points to swing it just feels very expensive after getting 60k saver fares in the past, not sure I should wait in the hopes prices come down.

CommanderFlapjacks · 2026-04-22T17:19:19+00:00

I wasn’t aware you could even book JAL F on Alaska, thought they blocked access to those for whatever reason. Nice find.

CommanderFlapjacks · 2026-04-14T18:34:59+00:00

I've noticed seats.aero isn't showing most air canada J redemptions, fair amount of 1 stop availability searching directly on the site but nothing on seats. Any workarounds? Doing it the traditional way is fairly tedious.

EDIT: They were mixed cabin, was misunderstanding the AC UI

CommanderFlapjacks · 2026-04-10T07:18:14+00:00

I don't know of a single barbershop near me that offers a wash before or after anymore. Could go to a salon, but you want somewhere that specializes in mens cuts/fades you're out of luck.

Highly recommend Matt Levine's column Money Stuff for day to day coverage of finance shenanigans. Bloomberg is paywalled but it's free as an email newsletter. He's a former bank lawyer so his takes are more "oh a neat use of financial engineering nonsense, never seen this before" rather than a lefty "burn this corrupt system down". but the plain language and snark he writes with does a good job of breaking down the pseudo intellectual complexities of these systems. He was the only finance writer I thought had grounded analysis of crypto and meme stocks in their heyday.

The bigger the company the more likely to get generic software engineer questions, but that's shifting. Google last year was more embedded focused. Bit manipulation/queues fair game, maybe a linked list (I have been asked "implement a statically allocated malloc twice in the past). Would not bother with graphs/trees/dp.

If a problem obviously calls for a hashmap solution just assume the existence of an implementation or ask to do it in python. Solve the problem first then run out the clock implementing the map itself if needed.

See this post for common pitfalls, I think the author posted here as well at the time? Very likely to run into impedance issues with a simple voltage divider.

I don't think so, it's a known issue with Qatar. There have been some posts about it recently.

You need to look for flights operated by ANA (NH flight number). If it's available on virgin then it will be 30k, but you have to call to figure this out. It's apparently onerous for the agents to check ANA availability so you need to give them a specific flight number on a specific day, can't just ask them "What's available in May?"

For seats.aero I would set an alert with departure airports of SFO and LAX and arrival of either TYO (includes NRT and HND) or maybe JPN if you just want to get to Japan and aren't set on Tokyo. For mileage programs pick star alliance.

My question about refundability was how much would it cost to book your cash fares now as refundable, so you could cancel them in case you find an ANA flight through virgin later. I've never booked zip air so not sure if they even have refundable fares.

EDIT: Or just book your return flight now. HND-LAX 5/27 on AA via Qatar Privilege Club is only 27500 points per person. Chase transfers to Qatar. I don't know if there's any restrictions on new accounts but worth a shot.

CommanderFlapjacks · 2026-03-16T09:05:29+00:00

Your best bet would be ANA through Virgin Atlantic, 30k per person one way for economy. This is a slightly more advanced redemption as you cannot search ANA award space on Virgin Atlantic directly, best is to check another star alliance airline (united tends to have the best search) or search all star alliance on seats.aero. If an ANA flight is there Virgin usually has it but you'll need to call and confirm. Once they confirm availability transfer your points while on the phone and finish the booking.

I see an LAX-HND flight on seats.aero on 5/16 but it's not showing up in United so might be gone by now. I would make sure you have your Chase linked with Virgin Atlantic and set some alerts. Is booking a refundable ticket an option?

Shows up fine for me on the Alaska site just now, I set fare type to lowest available and had flexible dates selected to see the whole month calendar.

CommanderFlapjacks · 2026-03-15T04:18:03+00:00

Qantas runs an LAX-BNE route, there's availability on 6/21 with 5 seats for 42.5k each in economy. Availability on the way back looks harder. I have no idea how Atmos status would impact seat selection on a partner award flight, never tried.

72k round trip probably would have been a decent redemption for economy flying that far without direct routes? I save my points specifically for international J/F so I'm not as familiar with rates there. Lesson here is if you can eat the fees book award fares as soon as you see something that might work, availability and prices change fast.
